Another nice thing in IDE's is auto-commenting and uncommenting text. It's surprisingly complicated when you consider that most languages have both line-style (//) and block-style (/* */) comments, and the particular characters used differ from language to language. So there's no one-liner to robustly comment things in Vim.

I just got tComment, though, and I like it. I've learned a couple things:
- installing vim plugins is often as easy as downloading a .vba file, opening it in vim, and typing ":so %".
- you can't remap the slash key. I'd like it to be the same as Eclipse, so ctrl-/ (or command-/ on mac) would toggle comments. But I don't think that can be done. (do correct me if I'm wrong.)

.vimrc: switching tabs in MacVim

I'm not yet all-command-line all-the-time. (ACLATT?) Sometimes I use, say, browsers. So I've been liking MacVim.

I also like how alt-tab (or command-tab) switches between windows, while control-tab switches between tabs in my browser window. When I found out that MacVim windows can have multiple tabs too, I wanted control-tab to work there too. Hence, the newest (MacVim-specific) addition to my .vimrc:

" In MacVim, you can have multiple tabs open. This mapping makes
" ctrl-tab switch between them, like browser tabs.
" I don't think it matters whether I use noremap or map, unless
" :tabnext gets bound to something else, which would be weird.
noremap <c-tab> :tabnext<cr>
