NumPad Problems When Using Vim over Tmux

I use vim as my main text editor, and I usually split the screen to edit a few buffers in parallel. To make resizing the windows faster, I mapped the numpad keys “/*-+” to resize the windows (see original vim tip here).

Recently, I started to use tmux, and opened vim, split the windows as usual, and tried to resize them. It didn’t work

I use Ubuntu 10.04 (Don’t remember the exotic name..), and I found that the latest tmux package in their repo is 1.1-1.

Anyway, version 1.1-1 has a bug with the NumPad. The solution is to download the source of tmux 1.2 and build it. It depends on libevent so you’ll need to get it first:

this is how to make it work:

1. sudo apt-get install libevent-dev

2. Get the source tarball of tmux from here.

3. tar xzf tmux-1.2.tar.gz

4. cd tmux-1.2

5. ./configure

6. make

7. sudo make install

Done. Now your life is better. Have fun
