Is there any way (keyboard shortcut) to shift an enitre piece of text?

Question

Okay I know I've worded the question horribly. We all know to make code visible in a box e.g:

\begin{document}

We have to shift it 4 spaces to the right so that it becomes:

\begin{document}

Is there any way to shift an entire group of text to the right instead of doing it line by line, like highlighting and then pressing the space bar, etc...

Answer 1

take a look at the line of icons above the answer box.

one of them is {} -- that indicates "code".

highlight the lines in your answer that you want presented as code, then click on the {}. done!

as noted by @JosephWright, Ctrl-K works as a shortcut after you've highlighted.
