Rocket.chat: Click markdown example toggle help dialog

[zxweed]

Your Rocket.Chat version: 0.27

It would be nice to have the ability to format the text not only by markdown codes typed on keyboard, but by selecting a fragment and mouse click on the help line (or by the hotkey like ctrl-b) too.

In general it would be outstanding to figure out how all the inline commands work. I could not figure out how kalatex works, tho i have a lot of experience with latex in general.

$ \lambda $
test

nothing seems to work haha :dancers:

@bott0r, you should inline the expression with "(" and ")" and enable the KaTeX plugin

@zxweed thanks!

If KaTeX (or other plugins) is enabled it should add an entry to the markdown help line
