UltraVNC

Well, in the ASCII table decimal 108 is lower-case "L" ("l"), for instance. but sending key code 108 via UVNC seems to trigger "Alt-H" on the server. so I guess a key code is not the same as an ASCII code. Any other (tested) hints? As you can see, the topic is not as trivial as it may seem.

Good to know, but you still have not explained how to find out the "nnn" of "Alt-nnn". I guess no normal user knows by heart all key codes, if any at all. Anyway, if the Scroll-Lock feature obsoletes the menu/button action "send custom key", it might be a good idea to remove that feature from UVNC ...

But the manual page does not mention how to find out the ASCII key code of the desired key. Can somebody point me to a description of how to do that and also add the corresponding information to the manual page?
