Keyboard entry notation
Following are abbreviations used for keystrokes:
Alt = Alternate
Ctrl = Control
BkSp = Backspace
Del = Delete
Ins = Insert
Esc = Escape
When commas are used to separate key strokes (e.g. Alt, F, O), those strokes are to be done in sequence with each key released after being typed. When plus signs are used to separate key strokes, those strokes are to be done in sequence, with each key held down (e.g. Ctrl+O).
Mouse notation
References to clicking or double-clicking with the mouse imply the left mouse button unless otherwise specified.
