Keyboard Control

    The inside cover of Mac OS X Power Tools contains a list of selected keyboard shorcuts in OS X. Below is a more complete list, divided into sections based on where they are applicable. For mouse/keyboard actions, check out the “Modified Mousing” link to the left. (Letter keys are printed here in CAPS for clarity — you do not need to press the shift key unless explicitly instructed.) (NOTE: This page is in the process of being updated for full Panther compatibility.)
