What Is The Hotkey For...

I am looking for the key combo to have the veiwed pattern play next. ie after the current pattern finishes playing. Also what are some other useful hotkeys for controlling the pattern sequencer?

go to the keyboard shortcuts in the Renoise key preferences and type “next” in the searchbox. There are a couple of sequencer related shortcut keys (also unbound by default) But i’m not sure whether they meet your desires.

Sounds like we are talking about scheduling the currently edited pattern? The keyboard shortcut is CTRL+SPACE.
Also, CTRL + SHIFT + SPACE to switch instantly (no scheduling)

And like vV suggest, try looking through the available keyboard shortcuts (or hit the “print” button to view them all in your browser)
