Yet i didnt find an option to launch a certain group of drones. Is that somehow possible ?
It would be nice, but there wouldn't be any way for your client to know which of your drones to deploy, unless it just sent out the top 5 in your list, like right clicking and "launch" does. It would be nice if you could assign hotkeys to drone group folders, but again, seems like it might be a lot of work to implement...
BTW, if you aren't using drone groups you are making your life harder. I usually put all of my drones into the following folders: DPS (hobs and hammerheads), ECM (ecm drones), FRIG (warriors - fast anti-frig drones), REPAIR, SENTRY, and a few others.
Another nice tip is to create a folder group called DAMAGED, and move armor and hull damaged drones in here if you have time during or between fights, so you don't relaunch damaged drones.
I admit my selection of R and G are not necessarily the best from a locational situation - to each their own - I tend to need visual reminders
I use "insert" for attack, "delete" for return and orbit, and "end" for return to bay. Although "home" would might make more sense for return to bay, but it's too late, my fingers have memorized the keys after too many years to change it now.
