The value has the grammar `Key[|OtherKey]`.
|
|
|
|
The list of key names is found in the header file
|
|
{file}`X11/keysymdef.h` (remove the
|
|
`XK_` prefix). Note that due to limitations
|
|
of X11 shifted keys must be specified as a shift key
|
|
followed by the key to be pressed rather than the actual
|
|
name of the character. For example to generate "{" the
|
|
expression `Shift_L|bracketleft` could be
|
|
used (assuming that you have a key with "{" above "[").
|
|
|
|
You can also specify keys in decimal (prefix #), octal (#0),
|
|
or hexadecimal (#0x). They will be interpreted as keycodes
|
|
unless no corresponding key name is found.
