always work. But in a terminal Vim gets a sequence of bytes and has to figure
out whether ALT was pressed or not.
+ If the terminal supports the modifyOtherKeys mode and it has been enabled,
+ then Vim can recognize more key combinations, see |modifyOtherKeys| below.
+
By default Vim assumes that pressing the ALT key sets the 8th bit of a typed
character. Most decent terminals can work that way, such as xterm, aterm and
rxvt. If your <A-k> mappings don't work it might be that the terminal is

! 1.11 MAPPING IN modifyOtherKeys mode *modifyOtherKeys*
!
! Xterm and a few other terminals can be put in a mode where keys with modifiers
! are sent with a special escape code. Vim recognizes these codes and can then
! make a difference between CTRL-H and Backspace, even when Backspace sends the
! character 8. And many more special keys.
!
! For xterm modifyOtherKeys is enabled in the builtin termcap entry. If this is
! not used you can enable modifyOtherKeys with these lines in your vimrc: >
! let &t_TI = "\<Esc>[>4;2m"
! let &t_TE = "\<Esc>[>4;m"
!
! In case the modifyOtherKeys mode causes problems you can disable it: >
! let &t_TI = ""
! let &t_TE = ""
! It does not take effect immediately. To have this work without restarting Vim
! execute a shell command, e.g.: `!ls`
!
! A known side effect effect is that in Insert mode the raw escape sequence is
! inserted after the CTRL-V key. This can be used to check whether
! modifyOtherKeys is enabled: In Insert mode type CTRL-V CTRL-V, if you get
! one byte then modifyOtherKeys is off, if you get <1b>27;5;118~ then it is on.
