Issue

From document:

$_READKEY (RO)

Get the key that is being pressed. Returns 0 if no key is pressed. 1 to 17 otherwise.

However with following:

OLED_CLEAR
OLED_CURSOR 0 0
OLED_PRINT $_READKEY
OLED_UPDATE

Regardless of saving $_READKEY value to other variable or not, it will always return 0.

(keycap intentionally rotated as I use duckypad horizontally)
