* we want to process text processing-oriented editor actions with higher priority than non-editor actions and all
* other editor actions with lower priority.
* <p/>
* Rationale: there is at least one commit-specific action that is mapped to the editor action by default
* (<code>'show commit messages history'</code> vs <code>'scroll to center'</code>). We want to process the former on target
* short key triggering. Another example is that {@code 'Ctrl+Shift+Right/Left Arrow'} shortcut is bound to
* <code>'expand/reduce selection by word'</code> editor action and <code>'change dialog width'</code> non-editor action
* and we want to use the first one.
