Unfortunately, I can't find any precise definition of a modifier key right now, so I don't know whether that's a complete list.Īppending | xargs xdotool keyup to the above pipeline will release all those keys. This works for all modifiers except CTRL. All possible modifiers which change the default modifier value are defined as constants in the Ke圜ombination class. All modifier keys which are not explicitly listed are set to the default RELEASED value. In old implementations and outdated specifications, it returned true when a modifier which is the typical modifier key for the shortcut key is. Constructs a Ke圜odeCombination for the specified main key and with the specified list of modifiers. event.getModifierState ('Accel') returns true when at least one of KeyboardEvent.ctrlKey or taKey is true. 56 that tells which bit corresponds to which modifier (bit 0 is L CTRL, bit 1 is L SHIFT, bit 2 is L ALT, bit 3 is L GUI, bit 4 is R CTRL, bit 5 is R SHIFT, bit 6 is R ALT, and bit 7 is R GUI). getModifierState () also accepts a deprecated virtual modifier named 'Accel'. Greetings, I am trying to get the key associated with the CTRL modifier with a KEYTYPED event. The state of the modifier keys are encoded as a bit field in the first byte (i.e., offset 0) of the keyboard input report. Which returns some keysyms that surely are modifiers. Greetings, I am trying to get the key associated with the CTRL modifier with a KEYTYPED event. ![]() One possible method of finding them is to parse keysymdef.h: grep '^#define' /usr/include/X11/keysymdef.h | sed -r 's/^#define XK_(\S*?).*$/\1/ ' | grep -E '_(L|R|Level.*)$' By voting up you can indicate which examples are most useful and appropriate. You can rate examples to help us improve the quality of examples. ![]() ![]() These are the top rated real world C (CSharp) examples of extracted from open source projects. One could use xdotool to achieve that easily, if not for that I have no idea what modifier keysyms are defined. Here are the examples of the csharp api class (, Modifiers) taken from open source projects. C (CSharp) KeyEventArgs - 30 examples found. Which sends a key release (for ISO_Level3_Shift, of course) event to the X server.īut you wanted a program to release all modifier keys. If you have xdotool installed, you could just simply use xdotool keyup ISO_Level3_Shift
