They're mostly the same, and they're customizable.
The only differences are:
To start prompting you press F9 instead of F8. (If you re-assign this key to a key with a type-able character, you'll have to press Ctrl+[key] to start the prompter.)
To move through markers, instead of the Home/End keys you use Ctrl+PageUp/Ctrl+PageDown. (If you re-assign these keys, the Ctrl modifier will apply to whichever key you've re-assigned to.)
To customize inputs go to:
Main menu (top left)
Control settings
Keyboard Inputs
An overlay will load giving you the ability to modify inputs. If you set an input as a key that has already been set, the new key won't be registered. You must first re-assign the key holding that value and then assign the new key to that key's old value.
Will the hotkeys/shortcuts be the same as those in Imaginary?
