Total Commander

Go to the multi-rename tool, and focus the field "Search for".
Type in anything you want (let's call this the original input).
Now press the Up or Down key (on the keyboard).

Result: your input is destroyed and replaced by whatever is in the history. The original input cannot be restored.

Expected: Original input should be restored when using the Up key to navigate to the top of the history list. Or literally *any* other method to get back to your original input.

Why: A regex is not easy to type in, and the up/down keys on the keyboard are easily pressed by accident.

Tested on TC 9.22a on Windows 10.

"Rename mask" field uses Ctrl+Up and Ctrl+Down. Other pull-down combobox fields in MRT should use the same keys.

This behaviour of "Up" and "Down" is the default behaviour of all comboboxes on Windows. I have changed it in the "Rename mask" field so you don't accidentally lose a complex rename mask. Currently I don't plan to change it in any other comboboxes because this behaviour is expected by most users.

So maybe it's better to allow users to globally choose combobox navigation keys? IMHO it would be more consistent behaviour.
