capslock|toggle follow mode
shift + 1 - 4|mute track
enter|open text editor (third column of track must be selected)
esc|close text editor
shift + enter|save expression in cell (while in text edit mode)
ctrl + c / v|copy / paste
shift + esc|open / close norns menu
ctrl + left / right|switch menu tabs
shift + up / down|fast nav between samples in params menu

Math
(+) (-) (*) (/) (%) (^) (=) (eq) (>) (<) (<=) (>=) (rnd)
Other
(list) (list?) (append) (apply) (begin) (car) (cdr) (cons)
(len) (get) (put) (nil?) (num?) (print) (concat) (map) (#t) (#f)
Examples
Functions can be executed either live in repl or from pattern cells.
```common-lisp
(def A 1) - sets symbol A to 1
(print "Hello") - double quotes for strings
(def A (lambda () (print "Hello"))) - defines a function (A) with no arguments
(def A (lambda (a b c) (+ a b c))) - defines a function (A) which takes 3 arguments and returns their sum.
(get '(1 2 3 4) 1) - returns first element from list
(bpm 120) - set bpm to 120
(jmp) - set current track position to the very beginning
(pos (rnd 1 99)) - set random start position for current sample
(atk 0.25) - set current sample attack to 0.25
```

copy-pasted expression cells are linked, so editing one would affect all others.
