This is a carryover from GalCiv2, and I can't believe they're still doing this.
The text entry has got slightly better but it's still not standard. Text entry should work just like it works in Windows, which considering Stardock does lots of development for Windows and undoubtably has some MS certified developers, they SHOULD know how to impliment standardized text entry. The normal text edit keys should all function normally. Why they go with some archaic custom system is beyond me. When I press SHIFT+HOME it should select all text for instant overwrite/delete. That kind of thing.
The bigger problem is ESC key behavior. 99.9% of windows programs and games use the same behavior. That is, when you hit escape, it closes the current window OR at the very least, it closes all open windows. Then, if there are no open windows, it opens the config/menu/whatever screen.
Why, WHY, is it that in GalCiv2 and Elemental hitting ESC always pops open the menu/config screen no matter how many windows you have open? Does anybody really want to see that screen when they're looking at some subwindow, like the research screen or something? I would think not.
When you've played games for 20+ years and been using Windows since it came out, your brain is completely trained to use the ESC key to back out of open windows. Why...is Stardock, a company that develops tons of stuff for windows, doing ESC behavior so whackily different?
Dig thru GalCiv2 forums - this is something that has come up several times in the past.
