I am trying to remap <PageUp>
key to call this function:
function! PageUp()
let l:line = line('.')
if(l:line != 1)
if(l:line != winline())
:set syntax=off
<PageUp>
:set syntax=on
else
normal! 1G
endif
endif
endfunction
but gvim complains that I cannot do it.
So what is the proper way to use the keys in a function ?

First of all, you use the PageUp key in Normal mode so the underlying functionality is a Normal mode command. You can't use such commands directly while in an Ex command-line or function/script. You need to use the Ex command :norm
for this.
Further, to use "key codes" (:h key-codes
) of non-printing characters like <PageUp>
you need to construct the :norm
command as an expression and pass it to the :exe
command (see last paragraph of :h :norm
).
That gives us:
:exe "norm <PageUp>"
The double quotes are required as is the to escape the keycode and indicate that you want the special meaning not the literal string "<PageUp>".
(Note: Usually we want to use norm!
instead of norm
in order to avoid conflicts with mappings but that's not a critical element of this answer so omitted.)

To send special key to :normal
, you need to get it's raw code by using "<key>"
notation.
exec "norm! <PageUp>"
You can also use raw code directly if you want(not recommended, hard to read):
norm! <80>kP
^----------<80> is 0x80
<80>kP
is raw code of <PageUp>
, you can enter it like this in normal mode:
"="<PageUp>"<cr>p
^----------press carriage return
If raw code of the key doesn't start with 0x80
, it's the same as terminal code (not sure), you can use the :h i_CTRL-V
to insert terminal code:
norm! <c-v><c-p>
^------------press ctrl-v ctrl-p
:h :exec
:h quote=
:h string
