To switch characters in GTA 5, just hold down the character switch button—which is Alt (Left) on PC, Down on the D-Pad for consoles (like PS4/PS5 or Xbox)—and a character wheel will appear. Use your joystick or arrow keys to select the character you want (Michael, Franklin, or Trevor). Release the button to switch instantly. Just make sure you're not in a mission or restricted area, as switching might be disabled there.
