Okay, so I use a CoolerMaster Quickfire TK and recently I have been having problems with some keys not working while others will. Most commonly it's the "R" key, so I popped out the key and cleaned off the dust and other debris found in the keyboard using compressed air.
After that the R key worked fine, but now whenever I press the "e" key it will print "er", the weird thing is, this will only work if I press the R key shortly before pressing the e key, resulting in something like: "rer".

Anyone know a fix for this (having to use copy+paste just to use the letter e)

I would be audacious enough to ask your full systems specs as well as asking you to make sure if your BIOS and remaining device drivers are up to date. If the issue was happening prior to the cleanup then it might be the device drivers assigned by your OS and if it got worse after the clean up then there might be an issue with the switch or the switch's housing. You may want to pull off both keycaps and see if individually pressing them recreates the issue you've stated above. Speaking of OS, are you running off Windows 10?
