Is there a way to force always show mnemonics in menus?

Question

I am making use of ContextMenuStrip in my program and apparently, it wont show its shortcut keys (mnemonics, those that should be shown as underlines under letters preceded

Answer 1

That is an operating system setting:

Control Panel\All Control Panel Items\Ease of Access Center\Make the keyboard easier to use\Make it easier to use keyboard shortcuts\Underline keyboard shortcuts and access keys.

Answer 2

Change the way the context menu is invoked. Don't show it manually, instead use something like:

textBoxSomething.ContextMenuStrip = yourContextMenuStrip;

In this case, if the user right-click on the text box (or other control you use), he will get the menu without mnemonics. But if he uses the keyboard context-menu-button to show the context menu, the mnemonics will be shown.
