What is the easiest/fastest way to move a keyframe to a specific frame?
In other words, is there a way to type in an absolute frame value with modal numinput (which uses the delta by default)? E.g. type G
140 to move a keyframe to frame
In the latest development version (after official 2.69), you can type with math, like this:
e.g.: If you want to move keyframe from 120 to 140, you can type G
Tip: it also supports copy/paste feature, which means, you can CtrlC on the current frame number displayed on Timeline header, then G
140-CtrlV), which makes it relatively quicker.
But indeed, a one-stop method may be useful here.
I think that the best you can do is type the preferred frame into the Timeline 'Current frame' field then apply a Snap to (ShiftS) frame function on the selected Keyframe.
It would be neat to have another snap to function as you suggest to reduce the amount of mouse clicks involved.
What you can do is:
Open a new editor window and set it to the Action Editor.
Go the Top of the Action Editor and select the frame you want to move.
Press G and click where you want it to be.
