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
