Editor windows in Keyman Developer supports standard Windows editing
keystrokes. Many file formats, including .kmn, .kps, .xml, .html, .js
and .json, support syntax highlighting. The text editor in Keyman uses
the Monaco component from Visual Studio Code, so all the functionality
available in that editor is also available here.

## Special Functionality

Aside from standard Windows keys, the following keystrokes are defined
for the editor:

| Keystroke      | Action        |
|----------------|---------------|
| <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>M</kbd> | Toggle Message Window visibility |
| <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>C</kbd> | Open Character Map    |
| <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>I</kbd> | Toggle Character Identifier visibility   |
| <kbd>Ctrl</kbd> + <kbd>F</kbd>                    | Find text     |
| <kbd>Ctrl</kbd> + <kbd>H</kbd>                    | Replace text  |
| <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>U</kbd> | Convert the selection to/from characters to code values|
