The editor can perform commands associated with keybindings through this method. The keydefinition argument is a string that represents the keybinding, something common in other application, here some examples.
There are common keys:
"<Ctrl>a", "c", "<Alt>b", "<Ctrl><Shift>1"
There are also special keys: Up Down Left Right Home End Prior Next Delete Insert Escape Backspace Tab Return KPAdd KPSubtract KPDivide
That can be used alone or with modifiers (Shift Ctrl Alt Super):
"<Super>Return", "Insert", "<Ctrl><Super>Backspace"
The command argument is a constant that represent the action to execute when the keystroke is done, available actions are:

The SCI_*EXTEND messages extend the selection.
The SCI_*RECTEXTEND messages extend the rectangular selection (and convert regular selection to rectangular one, if any).
The SCI_WORDPART* commands are used to move between word segments marked by capitalisation (aCamelCaseIdentifier) or underscores (an_under_bar_ident).
The SCI_HOME* commands move the caret to the start of the line, while the SCI_VCHOME*commands move the caret to the first non-blank character of the line (ie. just after the indentation) unless it is already there; in this case, it acts as SCI_HOME*.
The SCI_[HOME|LINEEND]DISPLAY* commands are used when in line wrap mode to allow movement to the start or end of display lines as opposed to the normal SCI_[HOME|LINEEND] commands which move to the start or end of document lines.
The SCI_[[VC]HOME|LINEEND]WRAP* commands are like their namesakes SCI_[[VC]HOME|LINEEND]* except they behave differently when word-wrap is enabled: They go first to the start / end of the display line, like SCI_[HOME|LINEEND]DISPLAY*, but if the cursor is already at the point, it goes on to the start or end of the document line, as appropriate for SCI_[[VC]HOME|LINEEND]*.
There’s also the SCI_NULL command that is no action.
