Mapping forward delete keys on OS X 10.9 Mavericks

When updating the OS, you need to check whether the programs you are using support it, but these days, you just update the OS without thinking about it.

I updated to 10.9 today, but I got a warning that DoubleCommand doesn't work while installing

Ugh, there is no forward delete key on the MacBook (a function that deletes the back of a character rather than deleting it while going backwards), and fn + Delete does a forward delete, but this is cumbersome. using doubleCommand open program (Now that I see this blog post in 2007 ^^) I am using the unused right option key by designating it as the forward delete key. Maybe it's because the right option key is to the left of the left and right arrow keys.

So I searched KeyRemap4MacBook I checked that the Iranian free program works in 10.9 and installed it.

2. If you want to assign to the right option key on the screen below, find 'Change Option_R Key (Right Option)' and check 'Option R to Forward Delete' below it. To link to another key, just find the key you want.




I couldn't find a paid one, but if the vendor doesn't do it, people release useful programs like this for free, so MacBook life seems to have become more convenient.
