- Click the Speedy Entry tool 
. Click the measure containing 
 the accidental. 
            - Position the insertion bar and crossbar on 
 the notehead in question. Use the arrow keys or the mouse.
 
            - Press the + key to raise the note’s 
 pitch, and the – key to lower it, by half steps. If you 
 press these keys repeatedly, you can add up to seven sharps or flats to 
 a note. If you press the CTRL key as you do so, all subsequent 
 notes on the same line or space in the measure also change. See Speedy Entry tool 
 for more accidental shortcuts.
