Unfortunatelly TestComplete editor is one of the worse I've ever used. There's support for changing tabs.... which is IE like and doesn't really work well (jumps from 1 to 3 back to 2 and the 6 tab... rather randomly). Laks lots of features Visual Studio, sublime Text 2, Notepad ++, etc support.
There's a couple of options here to make it easier for SmartBear to decide what to do:
Allow users to use any third party editors (can be done right now.... but it's not fully integrated for history, etc)
Add lots of key bindings and new hotkeys schemes VS like, Sublime Text 2 like, etc
PD. Idealy F5 for example should execute the test item/function I'm developing, not the whole project. You get the idea, right? The whole thing should be reviewed
