Considering the keyfob has 4 different functions via one button, and the iconography on the underside is fairly small and hard to read, and I don’t necessarily “practice” each of the functions everyday, I have come up with the following mnemonics to help me remember the number-of-clicks-commands. Your mileage may vary (and your imagination may come up with better mental-visual-aids):
lock: “l” has one point = 1 press
unlock: “u” has two points = 2 presses
frunk-hug: visualize hugging the frunk prior to opening or closing = long press
trunk-hello-hug: visualize tapping trunk to get its attention (because I’m approching it from behind) prior to giving it a hug = 1 press + long press
panic alarm: beating on a house front door to be let in (4 times) in a panic = 4 presses
lock: “l” has one point = 1 press
unlock: “u” has two points = 2 presses
frunk-hug: visualize hugging the frunk prior to opening or closing = long press
trunk-hello-hug: visualize tapping trunk to get its attention (because I’m approching it from behind) prior to giving it a hug = 1 press + long press
panic alarm: beating on a house front door to be let in (4 times) in a panic = 4 presses
