v2.7.3, cannot copy selected text. The first click on Zoom in / out show opposite actions.

Ctrl+C cannot copy selected text.
It's better to have a right-click menu to copy the selected text.

You first click Zoom in or Zoom out, nothing will happen.

After clicking Zoom in, then you click Zoom out, the result is Zoom in. vice versa.
In addition, it is better to support Ctrl+Wheel to do Zoom in & Zoom out,
