# How to make menus more responsive in Marlin 1.1.9

I have an AM8 with an MKS GEN 1.4 board with a Bowden extruder at the moment.

What I would like to do is to make my menus a bit more responsive, similar to what the guy at Lokster Space has done with ver 1.1.5 of Marlin with a tutorial how to do so. I've been through the file ultralcd.cpp but nothing matches what the tutorial is telling you to change.

Supposedly, it's no longer necessary in a recent Marlin version, already the inline bool handle_adc_keypad() function from ultralcd.cpp has implemented a smaller (100 ms) time delay. You could lower the value of #define ADC_MIN_KEY_DELAY 100 to #define ADC_MIN_KEY_DELAY 50 to see if that has any effect.
Also, look for next_button_update_ms = now + 300; (4 instances) which employs a 300 ms time delay after buttons are pressed. Try lowering the 300 ms time delay.
