how to use lightshot without print screen button

I've been using lightshot on windows for a couple years now and have loved it. I hope they consider improving that someday. Lightshot is an okay program that is 80% of the way there but that last 20% of missing user experience consideration is really noticeable. That's a shame because with some UX changes they could do it all in the one tool. I tried to use these features for a while but now I have mostly given up and use it for the one task of selecting an area of the screen to save as an image and then open that saved image in a different image editor to do the markup.

Adding text is infuriating because there is no editor box to allow changing font size/type - though I've heard there are some hidden hotkeys like scrollwheel for some of this but I haven't learned the secret language to make these hidden Lightshot features closer to useable. The color selector being colored pencils is strange and not very useful - I wish it had a simpler color selector or allowed hex codes/color names to ensure I was using the same colors consistently between screenshots. Selecting different tools barely shows a difference in the button highlighting or in the cursor so it's hard to tell what tool you're about to use. I often times find myself trying to draw a box to highlight something and instead it moves the frame of what's selected instead so the whole screenshot image changes. On the surface it does a similar job but the usability is much worse. Lightshot really makes me miss Greenshot.
