Trying to have Insert select files in checkbox mode

Help & Support
1

I noticed that in checkbox mode, the Insert key (Select NEXT=nodeselect) changes the visual selection, not the checkbox status. I thought I could change that with a plugin, but the solution I came out with (below) has the inconvenient of the screen flickering because of the checkbox off/on trick to find the focused element. Any idea to improve this?

function OnSelectAndNext(data) {
  var tab = data.func.sourcetab;
  if (tab.all.Count === 0)
    return;
  
  var cmd = data.func.command;
  if (cmd.IsSet('CHECKBOXMODE=off'))
    return;

  // remember which items were selected
  var was_selected = toArray(tab.selected);

  // turn checkbox mode off (it remembers the checkboxes)
  // after this, tab.selected reflects the visual selection
  cmd.RunCommand('Set CHECKBOXMODE=off');

  // select THIS: selects the focused item
  cmd.RunCommand('Select THIS');
  tab.selected.Update();
  var focused;
  if (tab.selected.Count === 0)
    focused = null;  // focus is on ".."
  else
    focused = tab.selected(0);

  // turn back checkbox mode on
  cmd.RunCommand('Set CHECKBOXMODE=on');

  // select or deselect the focused item unless it is ".."
  if (focused)
    if (includesItem(was_selected, focused))
      cmd.RunCommand('Select "' + focused.name + '" EXACT DESELECT');
    else
      cmd.RunCommand('Select "' + focused.name + '" EXACT');

  // move to the next item, unless we are at the end
  if (!focused || lastElement(tab.all).name !== focused.name)
    cmd.RunCommand('Select NEXT IGNORECHECKBOXMODE');
}

You shouldn’t need to turn checkbox mode on and off each time. The Select command has arguments to make it work on checkboxes.

I found the reverse (IGNORECHECKBOXMODE), but nothing else (except TOCHECKS and FROMCHECKS, of course).

Then how can I find out which item has the focus?

GetFocusItem
Returns an Item object representing the file or folder which has focus in the tab.

This seems to work, and it turns out no checkbox-specific argument is needed.

Ticks the checkbox for the item with focus:

function OnClick(clickData)
{
	var cmd = clickData.func.command;
	cmd.deselect = false;
	cmd.clearfiles();
	cmd.AddFile(clickData.func.sourcetab.GetFocusItem());
	cmd.RunCommand("Select FROMSCRIPT");
}
