On After Keystroke event is not generated:
- in list box columns method except when a cell is being edited (however it is generated in any cases in the list box method),
- when user modifications are not carried out using the keyboard (paste, drag-and-drop, checkbox, drop down list, combo box). To process these events, you must use
On After Edit.
When an entry requires a sequence of keystrokes, the
On Before Keystroke and [
On After Keystroke event] events are generated only when the entry is fully validaded by the user. The
Keystroke command returns the validated character. This case mainly occurs:
- when using "dead" keys such as ^ or ~: events are generated only when the extended character is eventuelly entered (e.g. "ê" or ñ),
- when an IME (Input Code Editor) displays an intermediary dialog box where the user can enter a combination of characters: events are generated only when the IME dialog is validated.
