I find I’m constantly adding/deleting frames to improve my spacing and timing, so I created a shortcut to move all keyframes after the current frame. I found the code through this post, but thought I’d type it up and make it simple to install for anyone else who may be interested.
In Maya go to Window -> Settings/Preferences -> Hot Key Editor
In Categories, go down to User and then click on New
Give it a name eg. plusOneFrame and paste this code into the command box:
Then in the text box in the Assign New Hotkey section, type in the shortcut you want to use for this action. I’ve used the = key, which was originally used to control the handle size (I might reassign another key for that).
Go through the process again to create a new hotkey for deleting a frame, but this time use this code in the command box:
I’ve used the – key as my shortcut.
Then click save.
Try it out by selecting your animated object or joint and pressing your new keyboard shortcuts.
