These options are used for manipulating the Timeline. Most of the Timeline functionality can be accessed through this menu.
= or Num + +
Extends the Timeline by adding a frame at the Current Frame Pointer.
- or Num + -
Shrinks the Timeline by removing the frame after the current key.
Increase scroll bar max frame
Ctrl + = or Ctrl + +
Extends the part of the Timeline available for editing.

Creates a new keyframe on the current frame.
If the current frame already has a key, it is removed.
Add/remove key on interval
Alt + F
Creates a keyframe for every frame on the selected interval.
If the interval already has only keys, they are removed.
Change IK/FK key
Shift + F

Change IK/FK key on interval
Alt + Shift + F
Switches keys on the selected interval between IK and FK.
Change to fulcrum key
Shift + R
Converts the selected keyframe into a fulcrum key.
Physical simulation is not applied to Fulcrum keys. Therefore, controllers on these keys can be stretched and squeezed.
Unlike the regular fixing tool (link), Fulcrum keys affect all the points on the track. They also work only with selected frames and interpolations associated with these frames.
Change to fulcrum key on interval
Alt + Shift + R
Converts every keyframe on a selected interval into fulcrum keys.
If every keyframe on the interval is already a fulcrum key, they are converted back into normal keyframes.
Adds a label to the selected keyframe, or removes it if the key already has one.
Plays the animation starting with the current frame.
Ctrl + X
Also plays the animation, but only keyframes are taken into account, while interpolations are ignored.
Ctrl + E
Combines selected Animation Tracks into one.
Move selected tracks up
