I always have used a shortkey to edit the sketch of a part (ALT+W) and that has always
worked both in part mode and assembly mode since far before 2000.
But since SW2019 when selecting the bos extrude in an assembly tree or part tree this
does not work anymore. I already sent that to Solidworks while doing beta but
it was not reproducable Solidworks told me. My VAR has reproduced it and got a SPR.
It seems to be a general problem where selection in the tree does not allow a
shortcut anymore. This has worked for more than 20 years.
I have shorcuts for almost any command and this is a serious regression for me.
Since Solidworks was not able to reproduce it I am trying to find what
could cause this behaviour.
Please leave a message if I you also see this new 2019 behaviour.
