Clear any key bindings

pass SWT.NULL for the action. For example, to remove the preceding insert/overwrite toggle, use this code:



styledText.setKeyBinding("i" | SWT.ALT, SWT.NULL);





Get the action bound to Alt+E

int altEAction = styledText.getKeyBinding("e" | SWT.ALT);

Passing a modifier constant isn"t necessary

int zAction = styledText.getKeyBinding("z");





Set a key binding

, call setKeyBinding() and pass both the key and the action. The possible values for the key are the same as for getKeyBinding(): characters or key constants from SWT, optionally bitwise ORed with modifier key constants. The possible values for the action are the constants from the ST class. For example, to bind the insert/overwrite toggle action to Alt+I, use this code



styledText.setKeyBinding("i" | SWT.ALT, ST.TOGGLE_OVERWRITE);
