dumb question about Illustrator

maybe someone can answer this. my Illustrator acts crazy sometimes, and some of my palletes (most importantly, my layer pallete) arent visible. they r up, but off of the screen somewhere. i know there is a key command to bring eveything into your window, but i dont remember. anyone know what it is?? its pissing me off.

Ctrl + Tab should switch you between windows within that program… if that doesn’t help then I dunno.
