Trigger symbol highlight on selection change

[AndreasArvidsson]

In vscode we can trigger editor.action.wordHighlight.trigger

Only on pre and post actions?

Yeah interesting to think through when to do it. And we'd prob need a flag on setSelections, otherwise ide wouldn't know it's pre / post

[AndreasArvidsson]

Or a separate editor method?

But an option is probably better.
