You do realize that this is not the only place where people post issues, right? I seem to recall this was an issue first raised back in RM8. There are tons of posts in regards to hot keys issues across at least three support channels. Very little effort has been made to fix many of those issues and some missing hot keys were finally added back after enough complaining.
The word selection feature I miss the most is a double click on a word and then a drag to select adjacent words.
I keep tryng it because it is do ingrained in my muscle memory- but of course it doesn’t work in RM.
Currently, there are two main places, other than direct to RootsMagic support request on their retail website. One is a FaceBook group RootsMagic Genealogy & Family Tree Software | Facebook the other is here in this Discourse forum. But, prior to this forum’s existence, there was a different official RootsMagic forum, for many many years, that ran different software and looked different.
