Controls

Everything is rebindable under Options → Controls → Command Block Staff Addon. Defaults:

Key	Action
Z + scroll	Change ability (1–6)
Left Alt	Change the current ability's mode
{{ "`" }} + scroll	Adjust the current ability's setting
V	Open the current ability's menu
F4	Clear electrified blocks
U	Undo the last command-ability action

Mouse depends on the ability — right-click is the main action, left-click the secondary/quick-chooser, and Shift + click does mode extras. Exact bindings are on each ability's page. When a mode has a Shift action, it prints a one-line hint at the top of the screen.
