Making Dexpot compatible with full screen RDP and SecondMonitorToolbar

Running the excellent Dexpot window manager for windows, along with the opensource Dual Monitor Taskbar can cause a few issues:

  1. It is not possible to switch virtual desktops on the client from within a remote desktop session
  2. The second monitor taskbar is on-top of the remote desktop client application

The remote desktop client for windows, allows ONLY the Caps-Lock key to be captured by other programs while in full screen, this is when the "Send windows shortcuts to remote system" is enabled.
Using the autohotkey scripts below you are able to switch desktops using the Cube from Dexpot using Ctrl+CapsLock. The use case for the script is as follows:

  1. Press and hold CTRL
  2. Press and RELEASE Caps-Lock
  3. Use the arrow left/right to navigate available desktops
  4. Release CTRL when you wish to switch to selected desktop

The requirements for the setup described here, are the following applications:

The script can also be found, downloaded and forked at github:

The code for the autohotkey is also outlined below. The implementation is:

  • Capture the pressing of CTRL+Caps-Lock
    Block the capture of this (we don't want to enable Caps-Lock)
  • If a remote desktop client is full screen, restore it to window mode, and enlarge the window to fill the screen
    We do this so the cube is still covered with the RDP client
  • Send Ctrl+Win+Arrow Up to launch the Cube
  • Capture the release of Ctrl nonblocking (allow other applications to see the event as well)
    If a Remote Desktop Window is present on the new virtual desktop make it full screen, and make the second monitor toolbar not topmost
    If no Remote Desktop Window is present, make the second monitor toolbar topmost
#SingleInstance force
; Usage: Press CTRL+CapsLock, hold CTRL and use arrow keys to navigate desktops
