Command Bar Thoughts

Was wondering, is there a way to set up Mush to where if you have typed something out in the command bar, you can just hit ESC to clear it all rather then hold Delete?

And is there a way to set it up to where if you type South, that South will not clear upon hitting Enter, but stay in the command bar until you clear it?\

And is there a way to set the command bar to remember commands in case you wanted scroll through your command history using the up and down arrow keys?

Hit Alt+0 there's an option for 'Keep Commands on Prompt Line' which if checked will keep whatever command you typed last in the prompt instead of clearing it. Also, Click the button labeled 'Keyboard preferences...' in the same dialog, In the deleting frame check 'Escape Deletes Typing' to make ESC clear the prompt, and if you also check 'Save Deleted Command' it'll save whatever was on the prompt in the command history before it clears the prompt.

many thanks
