Command Reference
Toolbar buttons, menu items and hotkeys are constructed from one or more commands. There
are two main types of commands, or instructions: internal and external.
- Internal commands are
the set of functions built-in to Opus - its "native language" if you like.
There are around 30 commands that make up the internal command set, and each
command takes one or more arguments that defines or modifies
its behavior.
- External commands are other programs outside of Opus. Using one or more
special control
codes, a toolbar button or hotkey can launch an external program and
pass information like the names of selected files to it.
The third type of instruction that can be used in a button or hotkey is the
command modifier. These are
not commands themselves - instead, they modify the behaviour of the overall
button.
