Resolved the clash between expand-region and wrap-region when using `='
to wrap inline code in org-mode. Now `C-\' starts expand-region modem
`\' expands further and `|' or `S-\' contracts and `<ESC>' key
exits/resets expand-region. In org-mode, now after selecting any word
with `C-\' and then pressing `=' will wrap that selection with `=' signs
