REAPER’s Action list Editor lets you assign keyboard shortcuts to any command or action, or sequence of actions, including many not shown on the MIDI Editor menus. Chapter 15 will show you how to do this, including adding actions to the MIDI Editor menus.
The Action list is displayed by choosing Show actions list from the Actions menu. It contains a whole load of assignable actions beyond those that are shown on REAPER’s menus. This means that you are able to create your own keyboard shortcuts for any of these actions, and even for sequences of actions.
Notice (below right) that within the MIDI Editor Action List you can assign MIDI commands and actions to keystrokes to specify their behavior when you are using the MIDI Editor. Quite a few have already had keys assigned to them and you can assign your own keys to other actions.
Here’s a simple example. If in the Action List filter box you type (for example) add note then only those actions which included these characters will be displayed (see right). One of these is
Add next note to
selection. You can assign this action a shortcut. You’ll see in Chapter 15 that the Actions List Editor lets you do much more than this. For example, you can:
-
Build a sequence of actions that can all be executed with a single keystroke.
-
Add actions and custom actions to your MIDI Editor toolbar and/or the MIDI editor Actions menu, and/or any of REAPER's MIDI Editor menu commands (File, Edit, Navigate. Options, etc.)
-
REAPER's MIDI Editor commands (such as Edit -> Delete events, Edit → Insert note, Edit → Quantize, Navigate → Select next note, Options → Correct overlapping notes when editing, etc.) can all be found in the Action list. In addition there are many hundreds of actions, some very precise, which are not shown on the menus. The table that follows should help guide you thru many of these.
