Every key may have a name and a number. The key number consists of digits but can have one letter of the Latin alphabet, at the end, e.g. 101A, 101B. The search can be performed by the name and by the number. Just enter any symbols. All coinciding variants will be filtered and displayed on the screen. You can activate the command for giving the key, directly from the search menu, or return back to the main menu to continue work.
