Hi,

I've found a workaround how to disable CTRL-ENTER in Lync (it would open an Audio call) (I have not tested it):
https://social.technet.microsoft.com/Forums/office/en-US/9121d154-4728-41b6-8fa1-04ed2fdec880/can-i-turn-off-lync-2013-keyboard-shortcuts?forum=ocsclients

Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Lync\DisabledShortcutKeysCheckBoxes
String Value: CtrlEnter
Value Data: 13,8

My question now is:

What other string values are valid? Can I enter  "Esc" ?And what does  13,8  mean?

I havent found anything in MSDN.

Thanks

The string value isn't what's important from what I understand, it's the value that's important. 13 means "Enter" and 8 refers to Ctrl. These are ascii codes.  8 typically means backspace, but in this case refers to Ctrl.

That said, there's no Ascii value we can use for the Escape key here (sometimes 27, but I don't think that works on this) so I don't think you can.  Here's an older thread where it's confirmed by Microsoft for an older client: https://social.technet.microsoft.com/Forums/lync/en-US/f59f12e4-3073-444d-8084-31766cab4756/disable-escape-key-in-office-communicator-20

Yep, I cannot block ESC. Have tried some combinations, but no success.
Thank you.
