some commands below refer to german PC-keyboard layout (I'm using Vice), I tried to translate them to c64 as good as possible

global

f1
f3
f5
f7


shift-C: change color setup
shift-T: change multispeed-type
shift-V: change global Volume/Speed/Filtersettings
ctrl-c: disk command
ctrl-l: load tune
ctrl-s: save tune
ctrl-d: directory


track edit
entf - copy buffer
shift-ü - paste buffer
shift-enter: enter sector edit
shift-s: enter sound editor
shift-m: switch to tune2 (f.e. to work on individual sectors)



sector edit

Shift-S: SND Command
Shift-D: DUR command
# : END Command
-: "-----" Command (Pause). these command is for conveniance in the editor only, it will be crunched by the packer remaining only snd+dur+end commands.

shift-.	transpose up



entf(delete) - copy buffer
shift Ü: (@) paste buffer

shift-ß (+): switch sector up
shift-´ (-): switch sector down

sound edit
shift-enter: enter wave-table
enter: leave to trackedit

wavetable-edit
shift-enter: leave to sound edit

format:
AD	attack/decay
SR	sustain/release
WV	pointer to wave table 
P1	pulse1 value (don't remember the usage)
P2	pulse2 value (don't remember the usage)
V1	Vibrato (don't remember the usage)
F1	Filter 1 (don't remember, probably start value, add value and speed)
F2	Filter 2
F3	Filter 3




general

3 different purpose tracks

1
vibrato channel

2
filter channel

3
drum-channel, all waves will be fixed frequency notes


known bugs
dur-commands always have to be followed by a note.

speed-settings are not saved with the tune, they have to be fixed in the tune after packing / adjusted after loading a tune in the editor.
$10e9 lda#$01 <- tunespeed.
