Insert keyframe with keyboard when entering values

If I am editing a field, e.g. X position, and I hit enter, I want to be able to use a modifier to also set a keyframe (single or group). Often the mouse is still over the field, so you can hit <kbd>I</kbd> afterwards, but not always. (Would probably help tablet users as well?) And this would also work from transform actions via e.g. the <kbd>G</kbd> hotkey.

E.g.

• 1.23 <kbd>Enter</kbd> -- just sets the position
• 1.23 <kbd>Alt</kbd>+<kbd>Enter</kbd> -- sets the position for all selected objects
• 1.23 <kbd>Shift</kbd>+<kbd>Enter</kbd> -- sets the position, and adds a keyframe
• 1.23 <kbd>Shift</kbd>+<kbd>Alt</kbd>+<kbd>Enter</kbd> -- sets the position and adds a keyframe for all selected objects
• <kbd>G</kbd> <kbd>X</kbd> 1.4 <kbd>Shift</kbd>+<kbd>Enter</kbd> -- translate 1.4 units, insert keyframe
