I got an HP laptop in university and someone coughed a mouthful of tea onto my keyboard a few months later. At first I kept "a" on my clipboard so I could paste it as needed while typing, but soon other keys followed. So my computer is over 6 years old and I've been typing for almost 6 years using:

• The 4 on my num pad as the A key
• The 7 on my numpad as Q
• The 5 on my numpad as tab
• The 2 on my numpad as Z
• The help/F1 is ESC
• The numpad 1 to type 1 and exclamation points

Recently, I've also changed the minus on my numpad to be ` (backtick). I don't have a capslock. Thankfully, the damage didn't continue to spread because I would have eventually run out of keys.

Sometimes I fantasize about someone calling me out on a weird typo so I can tell them about it.
