These keysyms are typically bound to the AltGr key in the X Window system. Opt on the client computer will be interpreted locally to produce extended characters, but will also send the ISO_Level3_Shift keysym for OptL, and Mode_switch for OptR. Controlling a Windows or Linux host computer from a Mac client computer To emulate on a Windows or Linux host.ĪltR and WinR can only be produced by changing the parameters from their defaults. OptR can only be produced by changing the parameters from their defaults. If you need to specifically press the left or right Cmd key, AltL maps to CmdL on the host computer, Win ( L or R) maps to CmdR. A similar restriction occurs across other VNC Servers - the solution is to either switch to a keyboard layout on the client computer that is capable of producing the required character, or to use the Mac's "special characters" dialog.



(It is most similar to the "AltGr" key on non-US PC keyboards.) Consequently, in version 4.5, the Mac's "Option/Alt" key is not mapped to the "Alt" keysyms over the RFB protocol. For example, the key marked "Alt" on modern Macs (also known as the "Option" key) performs a different function to the "Alt" key on PC keyboards. Some keys will be unique, and some keys with the same name perform will perform different functions. If you are connecting to a Mac from a Windows or Linux PC, or vice versa, the two computers are likely to have different keyboards. In VNC Enterprise Edition 4.5, it is intended that a VNC Viewer user should be able to press any key or key combination and the expected result will manifest itself seamlessly on the computer running VNC Server.
