is there anny software like filter keys but can select several letters

[kelapa]

hi,

so my keyboard broke downn, water spilled over and i try to vacuum it and it work againn.
the problem is the "n" key sometimes pressed twice as i onnly pressed once.
try the filter keys on, it fix, but the del/backspace will have the connsequences too.

how do i apply filter keys to "n" or there is way to apply the filter keys but add the "backspace" keys to exclusion?

it is easy to get rid of the keyboard and buy the new onne. but i using razer and it's cost quite a lot $200. so i want to use software first if i can.

thanks before

If you don't clean and dry you're going to loose your keyboard.
For a membrane keyboard, carefully open it. There will be 3 film layers plus a kind of silicon rubber for the keys.
Take them out from the control circuit board and wash them carefully with detergent and a soft foam. Let them dry separate from each other. Don't use a hair dryer.
Wash and dry the keyboard case and keys.
Assemble it again.
Did it many times.
