kate, when you applied alcohol to your keyboard, some of it probably seeped down in-between the the plastic layers that make up your keyboard's pressure switches. It is possible that this will dry after a month or so. Otherwise, it probably caused some corrosion on one of the button contacts or one of the trace wires. You have learned the hard way not to put liquid on your keybaord. To clean it, use compressed air. I have used something called "contact cleaner" on a regular cheap ass PC keyboard to fix a sticky key. Avoid removing your laptop keys. Many people do this and the key never goes back on correctly.
