J and K keys, but the keyframes have to be visible. These keys also move to the next marker or the next in or out point for a layer. Escentially you are moving between events in the timeline, but only visible events. The rest of the shortcuts are in the links Todd posted. Other early chemotherapy side effects include mouth sores, pain and hair loss, but these side effects typically develop in the weeks after treatment begins. It is difficult to determine the exact time frame for developing side effects of chemotherapy.
Chemotherapy is a powerful drug regimen that is used to kill cells that replicate rapidly. The chemotherapy process is physically demanding, and many patients notice side effects after a single treatment. There are a variety of different drugs used for chemotherapy. Depending on the choice of chemotherapy medication, the doctor may be able to predict the likelihood of the patient developing different side effects.
Types
Fatigue, nausea, vomiting, loss of appetite, diarrhea and fever are all common side effects that may occur after the first session of chemotherapy. Some people experience these symptoms immediately after their first session, while others may develop some or all of these side effects within hours of the completion of their first chemotherapy session. Other early chemotherapy side effects include mouth sores, pain and hair loss, but these side effects typically develop in the weeks after treatment begins.
Time Frame
It is difficult to determine the exact time frame for developing side effects of chemotherapy. The most well-known side effect, hair loss, does not normally start until 2 weeks after the first chemotherapy session. However, many people don't make it out of their first chemotherapy session without experiencing profound nausea and even vomiting or diarrhea. Fatigue typically develops soon after the end of the first chemotherapy session and may last a day or so after each treatment or plague the patient throughout the course of treatment.
Considerations
One side effect of chemotherapy that few people are able to escape is fatigue. Chemotherapy is typically given as an outpatient service, and many people mistakenly believe that because they are returning home the same day, they don't need to take any special considerations for their health. Having some help arranged at home can greatly reduce the fatigue levels of the chemotherapy patient. Someone to prepare proper meals and help with household chores will allow the patient to recover better between chemotherapy sessions.
Misconceptions
Often people believe that their hair will immediately fall out after their first chemotherapy session. Hair loss typically begins in the first month of treatment, but not immediately. The hair loss is also gradual. Losing your hair can be an emotional process, but the fact that it occurs gradually, over a period of weeks, may allow the patient time to come to terms with the process. Side effects that cancer patients should prepare for early in the treatment process are various digestive issues, including nausea and loss of appetite, and overwhelming fatigue. Preparing for these allows the patient to keep her strength up for the rigors of treatment.
Prevention/Solution
While there is no way to prevent side effects from chemotherapy, there are ways to manage them. By carefully monitoring how they feel, patients can work with their doctors to develop a plan for controlling fatigue, nausea and other digestive issues. After the initial chemotherapy session, the oncologist may provide medications that will lessen the effects of certain side effects or wait until the patient develops specific complaints before offering treatment.
Whilst there is no doubting the power and capability of After Effects for creating high quality, professional effects for any kind of video, one of the things that can seep up the process considerably is the use of keyboard shortcuts. Here I pick the top 10 most useful timesavers you can adopt in your After Effects workflow.
This is a basic tutorial about After Effects, professional video editing software. However, if video editing is new to you, consider Wondershare Filmora, which is a powerful but easy-to-use tool for users just starting out. Download the free trial version below.
Top 10 After Effects Shortcuts in Video Editing
1Layer Properties
My number one shortcut, simply because there isn’t a project that has ever been made where it could not be used, is the shortcuts for selecting a property from a layer without expanding it all fully.
This of course is rolling several keyboard commands into one entry, but I think separating these would be cheating a little, it really is only one shortcut. To use them, simply select the layer and press the appropriate button, that property will appear.
- A opens Anchor Point
- P opens Position
- S opens Scale
- T opens Opacity
- R opens Rotation
- U reveals all properties with a keyframe
- UU (double tap U) reveals all changed properties
2Add Expression
This one is another that gets a lot of use and so appears here, it is also true that it does save a lot of time in the menu system as well. Alt for Windows, Option for Mac, and click on the stopwatch for the property you are after.
Nice and simple of course, extremely useful and a timesaver for those complicated animations. You can also use the same shortcut to remove an expression as well.
3Creating a new layer
You may be noticing a theme here, something that is used a lot has a shortcut to get there quickly, and it is these things that shortcuts were invented for.
As you can see there are shortcuts for all the common layer types to allow you to quickly add a new layer to a project. Because solids have so many uses, vignettes and so on, they are well worth remembering. These are of course, the windows shortcuts, replace Control with Command for Mac aficionados.
Also note the shortcut to add an adjustment layer with ease at the bottom, again use Command in place of Control for Macs.
4Scale and reposition selected layers to fit composition
![After effects set keyframe hotkey After effects set keyframe hotkey](/uploads/1/2/6/3/126303884/596324642.png)
A real boon if you are using a variety of footage and layers from different sources, this clever little shortcut resizes and centers layers to fit into their composition. Here I set up a layer purposely larger than the composition, as you can see.
Simply pressing Control Alt and F (Command Option F for Macs) centers it on the composition frame and matches its size, all in one easy operation.
A great one, and as said, for those who regularly use a multitude of different types of sources a real help in the workflow.
5RAM Preview
This one is probably one of the more well-known shortcuts, hitting 0 on the keypad to start a RAM preview whether on mac or Windows platforms. However, with the prevalence of those wireless Mac keyboards that do not have a keypad, Adobe have seen fit to add in an additional shortcut for Mac only to get around this, which is Control and Zero.
That perhaps isn’t so well known and well worth a mention here.
6Move Timeline one frame
This one is a great asset if you are setting out a mask, adding in a motion blur or other motion graphic into a video or similar operation. Being able to advance or regress the timeline a single frame at a time comes in handy in many situations. For me, it is the uninterrupted work flow that really makes this one so useful, a simple key press and I’m onto the next frame without thinking, and that is the essence of a useful shortcut.
An additional one here, but not really a separate shortcut, is moving forward or backwards 10 frames at a time, just as useful in some circumstances and worth including here.
Use Control and the right or left arrow on PC, Command and the right or left arrow on Mac for a single frame, add shift to the combination to move 10 frames.
7Resize and reposition a layer
This is similar to the number four shortcut, in that it fits each layer into the composition, however this one maintains the original aspect ratio whilst it does it. This may not seem a big difference, but in terms of workflow for dealing with an array of input and output requirements, it really is.
If we go back to our previous situation with a layer that is bigger than the comp as we showed before.
Hitting Control+Alt+Shift+H (Command+Option+Shift+H for Mac) fits it to the comp but keeps the existing aspect ratio as we see here.
8Trim Layer
This is another simple action that can be done without interrupting a workflow by using the shortcut.
Trimming the layer to the timeline marker is a valuable editing tool when dealing with multiple layers designed to run concurrently rather than simultaneously.
This is very easy to do with this shortcut, you have your layer and you need it to stop at a certain time, simply set the timeline marker in the correct place
Then simply use Alt + [ or ] for windows, and Option +[ or ] on mac.
In this example I used the ] bracket to trim the end to the time marker, the [ would trim the beginning to that point.
9Timeline Zoom to Single Frames
If you are anything like me, you are constantly wanting to ping back and forth between a single frame view in timeline and the broader view as I go along. Whilst the slider bar is never far away, being able to zoom right in to the single frame, and then right back out to the entire composition duration is a boon to any workflow.
You can achieve this by simply using the ; key, on both Mac and windows.
10Moving the Timeline Marker to the layer in and out points
Our final one, and again another extremely useful shortcut for manipulating multiple layers and footage sequences without interrupting the workflow, if you need to quickly advance to the out point of your current layer, simply press O, to go to the in point, press I, it is the same for Mac and Windows, an easy one to remember and well worth doing so.
Of course, there are many more, Adobe publishes a full list of them in their support section, and on top of that it is worth remembering that you can customize every single shortcut in the program to suit your own working style if you wish to.
