Is it possible to map <C-;> to : in vim? - vim

I use capslock as control so it is more natural to use as : but noremap <C-;> : does not work. Is it possible to do such mapping in vim?

From Vim FAQ (also available through this nice plugin):
20.4. I am not able to create a mapping for the <xxx> key. What is wrong?
1) First make sure, the key is passed correctly to Vim. To determine if
this is the case, put Vim in Insert mode and then hit Ctrl-V (or
Ctrl-Q if your Ctrl-V is remapped to the paste operation (e.g. on
Windows if you are using the mswin.vim script file) followed by your
key.
If nothing appears in the buffer (and assuming that you have
'showcmd' on, ^V remains displayed near the bottom right of the Vim
screen), then Vim doesn't get your key correctly and there is nothing
to be done, other than selecting a different key for your mapping or
using GVim, which should recognise the key correctly.
Trying the above with <C-;> shows that it is not captured by vim/gvim...

Insert mode default keys in vim

The following items are useful to me in editing text, and I was wondering if vim had something for this built out of the box (though I didn't see it on the https://vimhelp.org/index.txt.html#index.txt page), or I had to create mappings for it:
Forward-delete a character. This is X in normal mode.
Forward-delete all text to the right of the cursor on the line. This is the inverse of ctrl-u.
Are either of these mappings available? And if not, are there 'standard' mappings for this that are common (for example, how it might be done in another unix program).
Note that this is the keyboard I have -- there is only one delete key (which acts like a normal backspace key) and there is no backspace key:
Note: for forward-delete, I am currently mapping ctrl-d as:
"Ctrl-d to forward-delete when in insert or command mode
noremap! <C-d> <Delete>
However, this interferes with the tab in insert mode (which I don't use) and the help-options in command mode (which I do use!) so I may have to modify this later, or hopefully someone suggests a better solution.
though I didn't see it on the https://vimhelp.org/index.txt.html#index.txt page
If you can't find it in the documentation, then it doesn't exist.
You can use fn+delete for "Forward-delete a character".
"Forward-delete all text to the right of the cursor on the line" is ctrl+k in MacOS, but Vim has its own use for that combo, :help i_ctrl-k so it is up to you to create a mapping for it.
Something like:
inoremap <key> <C-o>ld$

vimrc key mapping not working after the Esc key

map <Alt>q <Esc>la
This line in my vimrc seems not working after the Esc key. It do exits the insert mode but doesn't enter insert mode again. I also tried
inoremap <Alt>q <Esc>la
map <Alt>q <Esc><Ctrl-A>
map <Alt>q <Esc><Ctrl>A
Basically I want to have something within the normal typing position to have the same effect as key. Say
(i>5[cursor])
->
(i>5)[cursor]
Solution:
I figured out the problem. Its cuz my terminal doesn't properly recognize alt as the alt, instead as a system level alt somehow. see
Alt key shortcuts not working on gnome terminal with Vim
As far as I can see there are two problems:
<Alt> isn't a thing. If you want to map Alt+q, that's <M-q>.
:map doesn't apply to insert mode.
You haven't explained what you're trying to do, so I can't tell you what to do instead.

Vim commands containing `r` cause me to replace

I'm using vim and the python-mode extension, but I'm having a hard time using commands that contain r. It's causing vim to replace characters instead of executing my desired command.
Here is what the vim docs for python-mode say -
let g:pymode_rope_organize_imports_bind = '<C-c>ro'
So I'm doing CTRL-cro, but like I said, it's replacing which ever character I'm under with the letter o.
What am I missing?
It seems that your mapping is not being interpreted by Vim, so it only sees the Ctrl-c, which by default aborts the current action, then the replace command r (see :help r) followed by its "argument".
You could check if the mapping is defined with :map <c-c>.
If it is correctly defined it may be that your terminal is handling the Ctrl-c directly and not passing it to Vim, as stated in Vim FAQ 20.5 - Why does mapping the key not work?. In this case you could follow the instructions on Vim FAQ 20.4 - I am not able to create a mapping for the key. What is wrong?, in special:
1) First make sure, the key is passed correctly to Vim. To determine if
this is the case, put Vim in Insert mode and then hit Ctrl-V (or
Ctrl-Q if your Ctrl-V is remapped to the paste operation (e.g. on

key.
If nothing appears in the buffer (and assuming that you have
'showcmd' on, ^V remains displayed near the bottom right of the Vim
screen), then Vim doesn't get your key correctly and there is nothing
to be done, other than selecting a different key for your mapping or
using GVim, which should recognise the key correctly.

how to remap <C-;>

I want to use the following code to quickly go from insert mode -> command mode. The problem is it just doesnt seem to be registering my keys. I've tried with control (nothing happens) and i've also tried with command (D) and it just says spellcheck not activated.
" Quick command mode from insert
imap <C-;> <esc>:
How do i go about doing this? is there an easier vim way that I'm not aware of?
Certain Ctrl chords can't be mapped, including Ctrl-;.
This is mentioned in this FAQ, see also the Vim FAQ:
20.4. I am not able to create a mapping for the <xxx> key. What is wrong?
First make sure that the key is passed to Vim. In insert mode, press Ctrl-V
followed by the desired key. You should see the keycode corresponding to
the key. If you do see the keycode, then you can create a mapping for the
key using the following command:
:map <C-V><xxx> <your_command_to_be_mapped>
For more information, read
:help map-keys-fails
:help :map-special-keys
:help key-codes
The tip about trying to print the character using Ctrl-V is good to remember if you run into this problem with another key combo.
I tried it, however it doesn't seem to work, also as pb2q said, it just can't be mapped. But there are other ways to escape using a Ctrl key combination.
For example, you can also escape insert mode with the following key presses:
Ctrl-[
Ctrl-c
On OS X (I think Lion and above), you are able to map alt - ; using this method, alt - ; on OS X outputs รง, which you can map.
But at a MacBook, I prefer to use PCKeyboardHack to map caps lock to esc. Or at Windows, use a tool I've created myself for that or even Ctrl2Cap.
EDIT
oh sorry, I thought you wanted to switch to normal mode, that's why I talked about caps lock mappings.

mapping already exists for ^I in vim

I have added the following lines to the vimrc file so that i could use s-tab for indenting
map <esc>[Z <s-tab>
ounmap <esc>[Z
After i have added this , i get the following error. I use SnippetsEmu plugin
Error detected while processing function <SNR>15_SnipMapKeys:
line 10:
E227: mapping already exists for ^I
How do i solve this conflict.Why does this happen
A helpful way you can detect whether your version of vim is capable of differentiating between Tab and Shift-Tab is to:
Go into insert mode, press Ctrl-v* then Shift-Tab. I get <S-Tab> when I do that (gvim 7.2 on Windows XP).
If you don't get that then I don't think you can map Shift-Tab separately from Tab with your current setup.
*Ctrl-v will take the next key combination you press and output the key combination that vim actually sees.
EDIT: If you're sourced mswin.vim then you'll want to use Ctrl-q instead.
