modifierDown property

bool get modifierDown

True while the session is tracking the range-selection modifier gesture.

This is transient input state owned by the extension session, not a retained range flag, and is valid only for the current grid attachment.

Implementation

bool get modifierDown;

set modifierDown (bool value)

Updates the session-owned modifier gesture state.

Hosts may query the value during neutral keyboard navigation; extensions must clear it when the modifier is released, input is cancelled, or the session is reset.

Implementation

set modifierDown(bool value);
