I can't say what is in the original Default actions because my version is heavily customized, and for some reason I can't download the original from the Actions link (?? perhaps ./files/actions is no longer on the server ?) but certainly you can have those actions in your default set. You need merely associate the gesture of choice with the hotkey Ctrl-X for Cut and Del for Delete. I have them as follows:
<VERSION>StrokeIt .9.4</VERSION>
<APP name="Default">
Cut [Up] {
gesture = Up
Ctrl+X = keys, hotkey [CTRL_DOWN]X[CTRL_UP]
}
Delete [Down-Left] {
gesture = Down-Left
Del = keys, hotkey [DELETE]
}
</APP>
