From the menu: Studio One > Keyboard Shortcuts
Keyboard shortcuts are productivity upgrades for you. Learn the core shortcuts to save time/effort.
MAC: The “Studio One” menu is in the the far left, upper corner of the screen
PC: The menu is to the right, just to the left of “Help”
Search for “Record” and scroll down until you find the one in the “Transport” section.
On the right side, click in the blank space below the two existing KB Shortcuts, so that NO existing shortcuts are blue (selected).
Search for “Undo” and find the “Undo +Restart…” in the “Macro” section.
Set it to the “C” (lowercase) key, and IGNORE the warning that the “C” key is already in use for the Click (Metronome). In our VO context, we don’t use/need the default shortcut.
