Edits or inserts a key.
chkey [-f frame] [-t time] [-v lvalue] [-m lslope] [-a laccel] [-V rvalue] [-M rslope] [-A raccel] [-T tielist] [-F function] channel_patterns
If a key exists at the frame/time specified, then the values for that key will be modified. Otherwise a key will be set.
If both the left and right values are specified, the key will be untied at the point and the values altered independently. Otherwise, the effect depends on the tied state of the key.
The channel pattern specifies which channels will be affected by the command.
The expression function should usually be protected by '' to prevent any expansion of its contents. In the first example, the () would be expanded to give a syntax error on the command.
The value entering the key.
The slope entering the key.
The acceleration entering the key.
The value leaving the key.
The slope leaving the key.
The acceleration leaving the key.
Ties the options specified in the tielist, which is a list of characters (“amvAMV”) corresponding to the accel, slope, and value in and out options. Both the right and left settings will be locked together.
The expression function for the segment following the key.
chkey -f 1 -v 3 -F 'cubic()' geo*/t?Sets the value to 3 and expression function to cubic() for all channels matching geo*/t?.
