# Other percussion notation
## Diddles
Diddles can be added by using an eighth-note tremolo:
## Pedal lines
To add a vibraphone pedal line, see Pedal.
## Rolls
To add a drumroll to your score, see Tremolo.
## Sticking
To enter sticking symbols (R, L):
1. Select a start note;
2. From the menu, select `Add`→`Text`→`Sticking` (alternatively, set up a keyboard shortcut to do the same\
thing). The cursor positions itself ready to accept your keyboard input;
3. Input the letter just as you would normal text. To move forward or backwards to the next note, see Keyboard commands (chord symbols).
4. To exit, press `Esc`, or click on a blank section of the score.
