Doesn't work well with urxvt?

[osa1]

I just tried the keyboard example (in src/demo) with urxvt, and it doesn't work as well as it works on other terminals. For example, it can't detect keys F1 to F4. In addition, some keys are handled differently. For example, alt + arrow keys are detected as if only arrows are pressed, whereas in other terminals they're detected as shift + c, shift + d etc.

I'm wondering if this is expected?

Works fine on my machine. What TERM environment variable is set to when you're using urxvt?

Sorry for the noise. I had a hack in my .zshrc to set $TERM=xterm. I don't remember why I added that...
