I was having the same problem, and a little research led me to this article on the VMWare site
It shows how to modify the preferences.ini file to make the hotkey CTRL+ALT+SHIFT, and indicates that other key combinations can also be set.
CTRL+ALT+SHIFT was fine for me so I tried that and it works:
Purpose
This article provides steps to customize the hot key preferences in
VMware Server 2.0.
Resolution
The Remote Console does not provide an interface control to set the
hot key settings. You must configure hot keys in the user preferences
files.
To configure hot keys in the user preferences file:
Note: If you have other VMware products installed, these changes affect the preferences of those products as well.
1. Open the preferences file in a text editor.
The file is located in one of the following locations:
◦ %AppData%\VMware\preferences.ini
◦ ~/.vmware/preferences
- Add the following lines to the file:
pref.hotkey.gui = "false" pref.hotkey.shift = "true"
pref.hotkey.control = "true" pref.hotkey.alt = "true"
This combination sets the hot keys to CTRL + ALT + Shift . Other
settings yield different combinations.
- Save the file and restart the Remote Console.
