I find the article a bit confusing. Given this statement:
In addition, the keyboard is often more effective than the mouse for our work, since instead of floundering around in nested menus we can just type what we want. However, it’s worth noting that we don’t avoid the mouse because it is slow — if one wants to move the cursor to an arbitrary location elsewhere on the screen, one can often do so faster with a mouse than a keyboard. The problem is the transition from the keyboard to the mouse. It’s an expensive context switch, which should not be done lightly.
I don't really understand the following:
We then add syntax highlighting and hyperlinks, so you can easily navigate between man pages, or click on a grep result to visit that line in a file. Clicking on a hyperlinked directory in a file listing would reveal the contents of that directory in a nested list, slightly indented; clicking on a file would open it in a new tab.

Too much clicking for my taste.
