|
* if #GtkShorcutsShortcut:shortcut-type is set to #GTK_SHORTCUT_ACCELERATOR.
|
|
*
|
|
* The syntax of this property is (an extension of) the syntax understood by
|
|
* gtk_accelerator_parse(). Multiple accelerators can be specified by separating
|
|
* them with a space, but keep in mind that the available width is limited.
|
|
* It is also possible to specify ranges of shortcuts, using ... between the keys.
|
|
* Sequences of keys can be specified using a + or & between the keys.
|
|
*
|
|
* Examples:
|
|
* - A single shortcut: <ctl><alt>delete
|
|
* - Two alternative shortcuts: <shift>a Home
|
|
* - A range of shortcuts: <alt>1...<alt>9
|
|
* - Several keys pressed together: Control_L&Control_R
|
|
* - A sequence of shortcuts or keys: <ctl>c+<ctl>x
|
|
*
|
|
* Use + instead of & when the keys may (or have to be) pressed sequentially (e.g
|
|
* use t+t for 'press the t key twice').
|
|
*
|
|
* Note that <, > and & need to be escaped as <, > and & when used
|
|
* in .ui files.
