I would also like this feature very much. Could those keybindings be implemented with LUA scripting?
This topic is from 7 years ago. I do not know if anything has progressed since then. But what I do know, is that to do this through scripting, it is necessary to build the functions from scratch.
For example, if you want to transpose X note (D#5), a V value (12, a octave) from note column C (3) into pattern P (2), you must create a specific function for it. Then, that function can be triggered from a button, or from a specific keyboard command, or from an access within a Renoise drop-down list.And so with each and every one of the functions.
Through scripting, and according to the available API and the LUA language, you can do many things, but you have to build them.For example, in the following link you have a function that exactly mimics the jump of the Renoise step lenght, to navigate up or down:https://forum.renoise.com/t/improve-shortcuts-jump-to-0-16-32-48/49198
That same function, possibly can be written in another way. But it is necessary to create it, and then “do something” to be able to execute it…
