Keyboard shortcuts

Keys the console reserves, and the keys you can map yourself.

Two kinds of key work in LMX: the small set the console reserves for itself, and everything you map yourself with MAP KEY.

Reserved by the console

Anywhere

Key	Does
F1	Open this help
Ctrl+N	New show
Ctrl+O	Open a show
Ctrl+S	Save
Ctrl+Shift+S	Save As…
Ctrl+Z / Ctrl+Y	Undo / redo (`UNDO` · `REDO`)
Ctrl+F	(in the help window) Jump to the search box

Undo and redo leave a text field’s own undo alone - while you are typing in a box, Ctrl+Z still belongs to the box.

Playback, out of the box

Key	Does
Numpad 0	`GO`
Numpad Enter	`STOP`

These two are defaults, not stored mappings, so they work in a show of any age. Map either key to something else and your mapping wins; MAP KEY NUM0 REMOVE turns the default off for that show, and MAP KEY NUM0 GO puts it back. SHOW MAP lists them, marked (default).

In the command line

Key	Does
Enter	Run the command
Tab	Complete the current word, or cycle the options
Up / Down	Walk back and forth through this session’s commands

In tables

Key / gesture	Does
Click	Select that row
Ctrl+click	Add or remove one row from the selection
Shift+click	Select the run between the last click and this one
Double-click a cell	Edit it in place
Enter	Commit the edit
Esc	Abandon the edit and put the old value back

On dials and sliders

Held while dragging	Effect
Ctrl	Fine - small steps for precise angles
Shift	Coarse - large steps to cross the range quickly

On Quick Access tiles

Gesture	Effect
Click	Apply, releasing whatever else in that row was on
Ctrl+click or Shift+click	Stack instead of replacing
Right-click and drag	Apply at a percentage, live

Keys you map yourself

MAP KEY binds a key to GO, STOP, tap tempo, or any command at all:

MAP KEY NUM0 GO
MAP KEY NUMENTER STOP
MAP KEY NUM5 TAP FREQUENCY 1
MAP KEY CTRL B COMMAND "BLACKOUT" ENTER
MAP KEY F9 COMMAND "GO "                # leaves it in the command line to finish
MAP KEY DETECT GO                       # press the key you want
SHOW MAP
MAP KEY NUM0 REMOVE

Which keys are allowed bare (no modifier): F1–F12, every numpad key (NUM0–NUM9, NUM+, NUM-, NUM*, NUM/, NUM., NUMENTER), and HOME END PGUP PGDN INSERT DELETE TAB ESC.

Everything else needs CTRL or ALT - characters, arrows, ENTER, BACKSPACE, SPACE - so that ordinary typing and field navigation are never hijacked.

The numpad is the obvious home for playback: it is a self-contained block of keys you can find without looking. That is why NUM0 and NUMENTER are already bound to GO and STOP before you map anything.
