# Other percussion notation
## Diddles
Diddles can be added by using an eighth-note tremolo:
## Pedal lines
To add a vibraphone pedal line, see [Pedal](https://handbook.musescore.org/idiomatic-notation/keyboard/pedal).
## Rolls
To add a drumroll to your score, see [Tremolo](https://handbook.musescore.org/notation/expressive-markings/tremolos-and-rolls).
## 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](https://handbook.musescore.org/customization/preferences#shortcuts) 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)](https://handbook.musescore.org/text/chord-symbols#navigation-commands).
4. To exit, press Esc, or click on a blank section of the score.
