keymapping - Vim - How do I use a key mapping command like <C-L>? -

-

i'm else has had question, , may repeat, i'm not sure call command <c-l> , haven't had luck finding existing question. if duplicate, please redirect me.

the question arises vimrc section reads this:

" map <c-l> (redraw screen) turn off search highlighting until " next search nnoremap <c-l> :nohl<cr><c-l>

so combination of keys press (in mode) input <c-l> mapping?

in line:

nnoremap <c-l> :nohl<cr><c-l>

nnoremap means normal no-recursive map <c-l>... means, if press ctrl + l in normal mode, mapped key-strokes applied.

<c-l> means ctrl + l

if type 

:h control

you can see keycodes:

<c-...>     control-key         *control* *ctrl* *<c-*

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
