Select next chord after current selection

I need my plugin to select the next chord after the current selected chord(s):

I know that I can access and set the selection with curScore.selection.select(element) (documentation).

But how to get the next chord element after the current selection? I tried this:

    function proceedToNextChord() {
        var cursor = curScore.newCursor()
        cursor.rewind(2) // goto end of selection
        console.log(cursor.next()) // next segment, logs false ("end of score")
        var element = cursor.element // returns null
        if (element) {
            curScore.selection.select(element)
        }
    }

But it looks like cursor.next() cannot go beyond the current selection. Any ideas on how to get the next chord?

Wouldn't cmd("next-chord") work out? Then select-next followed by select-prev will likely select that.

Just like how I would do it in the UI manually:
1. Press right arrow key
2. Press Shift+right arrow (selects this + next)
3. Press Shift+left arrow (removes next from selection again)

Thanks jeetee, good idea! I wasn't aware of cmd().

It works like this:

    function proceedToNextChord() {
        cmd('next-chord')
        cmd('select-next-chord')
        cmd('select-prev-chord')
    }

BTW: The only list of commands I've found so far is here at GitHub. I didn't found official documentation.

That txt is old and obsolete.

Here's the real 3.x list: https://github.com/musescore/MuseScore/blob/3.x/mscore/shortcut.cpp#L30
The action name you have to place as the argument for cmd() is the 3rd entry into the struct

Thanks!

PS: To get a list of all commands:

awk '/^Shortcut/{s=1}; s&&/^ *"[a-z-]+"/{gsub(/[ ,"]/, ""); print}' < shortcut.cpp
