If developer mode is enabled, you get a few extra keybinds for testing songs:
E = Edit Mode
R = Restart
1 = Restart as Kris
2 = Restart as Susie
3 = Restart as Ralsei
4 = Restart with all characters set to "demo" (their parts will be auto-played)
In the chart editor:
Left Click
Click on chart = Place note
Drag from note = Extend Note
Click/Drag timeline (red line on the right) = Go to position in song
Hold Right Click on chart = Erase notes
Hold Shift = Special note (For Kris and Susie, they play a different animation when they hit special notes. For Ralsei, special notes are the big notes that take up all three lanes)
Hold Alt = Snap to 1/3 beats instead of 1/4 beats
Space = Pause/Unpause music
Backspace = Reverse music
S = Save
P = Play Mode
