Excluding Keypresses From History

[akalabeth]

Hey, back when I had a job my supervisor gave me some script which I could add to the hotkeys so that when I pressed them they wouldn't be counted in the history. I added this to the uh <> hotkeys, so I could step forward and backward along the timeline and then when I hit Z it wouldn't go through all that garbage.

Does anyone know what to add to the hotkey to enable this? I should have wrote it down.

Second question, with AutoTangent. Also at work part of the hotkey or something had it such that, when I used my hotkey the window for autotangent only shows up the first time. After that, it will do it automatically. Does anyone know how I can do this? Ie, hit autotangent, then the window pops up and you have to hit "autotangent" button again. Then after that, just do my hotkey like Alt+W and then it does it without the window.

Thanks

I remeber that i have posted one of theese on the forum so do search. I think it was about undo of timeline moves.
anyway theres a conmmend called undoInfo thet enables you to disable undo, the command itself doesnt undo so if you wrap raound your command with undo off undo on it doesn't undo.

But please be careful with this, some commands that affect more serious parts of maya state MUST be undoable or maya will just flush the undo.

so:

undoInfo -state off;
... your stuff here...
undoInfo -state on;

PS: maya accepts on,true,!00 as true whereas off,talse,0 is false
