Issue with Delphi Menu

This is because of TMainMenu.AutoHotkeys. By default, the value of this property is maAutomatic, which means that the menu will automatically choose accelerator keys for your menu items.

For instance, in a typical English application, you might get a menu like this:

Notice the underlined characters. These are used to access the menu using the keyboard. For instance, to open the File menu, I can press Alt+F. And once the File menu is open, I can press the key corresponding to the underlined character in the caption of the menu item I wish to invoke.

For keyboard users like myself, such accelerators are extremely important. I use them all the time. I could use the mouse instead, but that would slow me down tremendously. (For instance, in the application in the screenshot, I am very used to press Alt+E, O to open the Sort Lines dialog box. That takes about 0.2 seconds. If I had to use the mouse, it would take much longer!)

Now, in your case, there aren't any Latin letters to underline, so instead the RTL adds these parentheses (with the Latin letter being the accelerator), so you still can access the menus using the keyboard.

I have very little experience with non-Latin-based versions of Windows, but I do believe menus like these are standard. If I were a Chinese or Arabic user (for instance), I think I would refuse to use an application without these. If I cannot access GUI menus and controls with the keyboard, I get really annoyed.

Still, if you insist, you can set AutoHotkeys to maManual.
