Is it possible to include multiple file types when using the `FileType` event?

Question

For example, I'd like to map a key when in a tex-like file, which includes many different flavor of tex files. Do I have to use multiple commands like this?

au FileType tex nm <C-H> <Plug>IMAP_JumpForward
au FileType latex nm <C-H> <Plug>IMAP_JumpForward
au FileType context nm <C-H> <Plug>IMAP_JumpForward
au FileType plaintex nm <C-H> <Plug>IMAP_JumpForward
...

Absolutely:

au FileType tex,latex,context,plaintex nm <C-H> <Plug>IMAP_JumpForward

Some thoughts:

Should be using a buffer local mapping instead of a global mapping
Using short names has only cons and zero pros. Don't.
This autocmd should be in a group
Autocmd's should be cleared (inside a group) so that re-sourcing is not a problem
Maybe use a after ftplugin script. e.g. ~/.vim/after/ftplugin/tex.vim instead of an :autocmd as they are easier to manage
look into romainl's idiomatic vimrc for more vimrc do's/don't's

Cleaned up version:

augroup tex_mappings
    autocmd!
    autocmd FileType tex,latex,context,plaintex nmap <buffer> <c-h> <Plug>IMAP_JumpForward
augroup END

Alternatively add the following to ~/.vim/after/ftplugin/txt.vim:

nmap <buffer> <c-h> <Plug>IMAP_JumpForward

Note: with the ftplugin approach you will need to add this line for each FileType (or use :source)
