Keybord shortcuts in code editor (Monaco) not working

Radzen Blazor Studio
1

I've started testing Radzen Blazor Studio a few days ago and quickly realized that it uses Monaco as the code editor engine (same engine as VS Code). Coming from a VS Code background, this made me really happy. But what really bothers me is that all the shortcuts that are standard in Monaco, like:

  • Alt + Up/Down to swap lines,
  • Alt + Shift + Up/Down to duplicate lines,
  • Alt + Ctrl + Up/Down to expand the cursor to multi-cursor mode,
  • Ctrl + Shift + L to select every occurrence of the selected text,
  • Ctrl + Click on symbol, or F12 to navigate to its definition,
  • Ctrl + # to toggle line comment,
  • probably more,

don't work. And even when you have multiple cursors (using Middle-click + Drag or Alt + Left-click), everytime you want to jump hole words using Ctrl + left/right, it collapses to just one cursor. I know many other apps using Monaco and this works for all of them. I can't imagine anyone deliberately removing it. I looked for settings and everything, but still found no reason why it's not there.

Test Monaco here: Monaco Editor

(Just for completeness, Visual Studio style shortcuts also don't work)

Hi @Paul_Suckow,

Indeed we haven't enabled all Monaco features. We are including a subset of them in order to improve build and load times. It seems those advanced shortcuts are some of the features omitted.

We will enable some of the shortcuts with the next release:

  • Alt + Up/Down to swap lines,
  • Alt + Shift + Up/Down to duplicate lines,
  • Alt + Ctrl + Up/Down to expand the cursor to multi-cursor mode,
  • Ctrl + Shift + L to select every occurrence of the selected text,
    • Ctrl + / to toggle line comment,

We have also enabled multiple cursors.
