Backtick (`) in insert mode works strangely when I edit a TeX file on Vim.
I am expecting that when I type `a Vim displays `a and when I type `b it displays `b, and so on.
But, in fact, when I type `a it displays only a and when I type `b it displays only b.
Furthermore, when I type, for example, `j it displays `j, as I expected.
Some letters following a backtick will be displayed with a backtick (as I expect), and others without a backtick (strange behavior).
Here is lists showing which letters follow a backtick and which letters replace a backtick.
following
// `j becomes `j
j o v B C H I J K M
N O R T V Z 1 2 3 4
5 7 9 ! @ # $ % ^ &
- _ + | ~ { } ; : '
" , / ?
Space(0x20)
replacing
// `a becomes a
a b c d e f g h i k
l m n p q r s t u w
x y z A D E F G L P
Q S U W X Y 6 8 0 *
( ) = \ ` [ ] . < >
This behavior appears only when I am editing a TeX file and in insert mode. In normal mode I do jump to the marked position, and on Markdown my Vim displays a certain number of backticks.
Why does it work in such a way and What should I do to have it work in a certain way?
