In the pattern session, it says to use [/] to toggle play/mute for a selected track - doesn’t do anything here …
Also, is a vertical pattern “track” selected if title highlighted in green ? If so, I can only seem to select it if in the mixer page. The hand icon in the pattern editor page doesn’t allow me to click on a pattern header to select it…
right click on a track, then select “track”, there you will find “mute”. the shortcut is displayed next to it.
here it is “#”, what i think is the default value nowadays.
or you could go into edit->preferences->keys
there you can edit and look up all shortcut keys. you can also export a list of all your current shortcuts via the “print” button on that page. (works with firefox. just have your favourite browser open at the time. there’s also a list somewhere of browsers that support this feature. but the “mainstream” browsers all do, sooooo…)
and as far as track selection is concerned: either you switch tracks using “tab” and “shift+tab” OR you double click in the track (meaning not an its name). third mouse button (≙ mouse wheel) also worx.
