I have just installed the LTR version of QGIS (3.4.10) and am having trouble telling QGIS when I have finished a polygon. In fact, I can't.
It used to be in earlier versions that to end a polygon you would type ctrl-click. This is the equivalent to right-click in PCs.
It doesn't work at all in QGIS3.4.10.
Has anybody else encountered the same problem? What is the solution?
[I have tried ctrl-click in other apps such as word, and it functions as it should. I have also completely rebooted the computer but that doesn't help. I am running OS Mojave--10.14.6]
