audacity keyboard shortcuts on mac for "transport > skip to start" and "transport > skip to end"

i was messing around in audacity on my mac and couldn't figure out the keyboard shortcut to move the cursor (in logic it's called "playhead position") to the start or end of the track. the Transport menu in audacity just shows diagonal-looking arrows pointing top left and bottom right:

i tried combining arrows with different function keys and found out that on mac you use the fn (function) key with the arrow keys:

skip to start (left arrow):
fn + <--

skip to start (right arrow):
fn + -->

then i found out you can also just use the letters j (track start) and k (track end)

Batch-convert multiple wav files to flac on mac: xACT (Audio compression toolkit)

If you want to convert a folder of audio files (WAV, AIF, etc) on mac to e.g. FLAC, then install xACT.

This makes my life easier when I publish samples on ccMixter. I export Regions or Tracks from Logic Pro X as wav, then open them all at once in xACT, then batch-convert them to FLAC because ccMixter wants users to upload files as FLAC.

Please upload a preview in 128k MP3 and individual tracks as FLAC. Upload small samples as FLAC in a ZIP.
