title: VSCode colon open command palette
body: <p>On my Mac OS, I install VIM for vs code.</p>
  <p>After press colon ':', vs code command palette pops up, no enter vim command on status bar. And on status bar a string 'workbench.action.showCommands' shows.  I think that indicates somewhere I set up colon as a shortcut to vscode command.</p>
  <p>VIM extension works fine on my Windows.</p>
  <p>Where can I find the wrong settings and get vim colon work?</p>
