✅ Support for parameters when binding commands to hotkeys

Is that explained anywhere in the help-file anywhere?

Dialog box: Configuration - Change button bar

%|envvar|
Insert environment variable envvar in the parameters field. Using %envvar% directly isn't possible, because the % sign is already used for placeholders. Therefore this modified syntax needs to be used. The "command" field still uses the normal %envvar% field.
