Understanding Keyboard Input To Virtual Desktops
By default, when you use a virtual desktop all key presses are directed to it (not the local computer) with the following exceptions:

  • Windows logo key+L is directed to the local computer.
  • CTRL+ALT+DELETE is directed to the local computer except in some cases if you use the Citrix Desktop Lock.
  • Key presses that activate StickyKeys, FilterKeys, and ToggleKeys (Microsoft accessibility features) are normally directed to the local computer.
  • As an accessibility feature of the Desktop Viewer, pressing CTRL+ALT+BREAK displays the Desktop Viewer toolbar buttons in a pop-up window.
  • Windows key combinations (for example, CTRL+ESC and ALT+TAB) are directed according to the settings that your help desk has selected.

Note: By default, if the Desktop Viewer is maximized, ALT+TAB switches focus between windows inside the session. If the Desktop Viewer is displayed in a window, ALT+TAB switches focus between windows outside the session.
Hotkey sequences are key combinations designed by Citrix. For example, the CTRL+F1 sequence reproduces CTRL+ALT+DELETE, and SHIFT+F2 switches applications between full-screen and windowed mode. You can use hotkey sequences with virtual desktops in many, but not all, setups. For example, they work with your hosted applications.
