I doubt you can get any significant improvement that way, but unless I am miscounting<p><pre><code>  Save file and Exit=Ctrl-K X    Exit Without Saving=Ctrl-C    Help=Ctrl-K H
</code></pre>
fits in that space. I doubt it will help much because people will have forgotten the key combinations seconds after typing the first character, and even if they do remember them, they will not become as engrained as the keystrokes they know work in other programs.<p>I am pessimistic because I see three problems with Control-K X for &#x27;normal&#x27; users:<p>- they aren&#x27;t used to the tiny mode that Control-X introduces (it wouldn&#x27;t even surprise me if interviewing a few &#x27;normal users&#x27; would show that they do not know what &quot;Ctrl-K X&quot; means)<p>- most other applications separate the &#x27;save&#x27; command from the &#x27;exit&#x27; command (web and phone apps are exceptions, but they don&#x27;t use explicit save at all)<p>- it&#x27;s not control-S (unfair? Maybe, but I would call it realistic)<p>I doubt reminding them &quot;hey, this program is different&quot; at startup will help much for that.<p>Disclaimer: I&#x27;m not a professional in this field and I am wildly guessing at the target audience for a simple text editor.
