I have the following problem. I have reassigned my action key from "E" to "Tab". I can access a terminal to change loadouts and/or vehicles as normal with the "Tab" key, but can't exit from the terminal by using it, even though it says ">> RESUPPLY [Tab] <<" on the loadout screen. If I map the key to back to "E" it works as normal. This makes resupplying and quick changing loadouts in the heat of the battle difficult since I can't just tap the action key twice or use the class quick keys + the action key to change class. Is it just me or has anyone got similar issues?
That's an old problem and comes from the fact that loadout screens are a different keybind environment than "General", "Infantry", "Vehicle" or "Aircraft". Your number keys and class selection keys do different things in that window than in anywhere else in the game. It would really need it's own keybind page, and as it is now some keys just can't be used in it as they are hard coded to do something else.
