<p>Hi,<br>
</p>
<p>You have various selection tools in the GUI. (yellow box Icon
with an arrow). If you use shift + left mouse click, you can add
to the current selection. I think it is Ctlt + left mouse click
in some version of QGIS.<br>

<div>Hi All,</div>
<div><br>
</div>
<div>I'm doing some work that entails fixing up some
digitization based on per-pixel image classification.
Sometimes there are polygons with lots of rings contained, so
I'm using the Delete Ring tool, but that requires clicking on
every individual ring. Is there a way to delete multiple rings
at one time via clicking/dragging with a keyboard key held or
anything like that? <br>
</div>
<div>Thanks!</div>
