Canvas keyboard controls: use left and right bracket or Page Up and Page Down to select items. Arrow keys move the selection. Shift plus arrows resize it. Comma and period rotate images. Insert creates a hotspot in hotspot mode. In draw mode arrows position the drawing cursor and Enter applies the chosen tool. Delete removes a selected object or hotspot. In test mode, select hotspots with the same selection keys and press Enter or Space to activate one. Escape exits test mode.
