Ever been defending a base and you died, but your gang won't know what hit them because they're in the flag room? There's not enough time to go "Ah! There's a horde of attackers, incoming! Get ready!" if your in a base. So, use keyboard shortcuts. Navigate to Settings > General > Keyboard > Shortcuts > Add New Shortcut.

Here you can type "Flag!" or even "F" and it will replace it with anything you wish, like the example above. I don't know if anyone uses this. If a lot of people already do, then this sure was a waste of time. Ah well, enjoy anyways.  

This should be in FAQs and Guides, but this wasn't a waste of time. A few threads concerning this have popped up. I personally have always used them; when I need help, I say "sgpr" for "showguild Player Relations" and back when I played events a lot I'd say "sget" for "showguild Events Team."

Also omw is great for basing (it's for On my way! and is a preset)  

Oh, yeah. I never thought of those!  

Meh the saying "flag" is nearly useless because once you say it you lose the base.
