I select all the time, using either mouse or a keyboard. In addition to the mentioned problems with JS popups on click on NYTimes et al, there is another set of annoyances due to invasive keyboard shortcuts.

I select text from kbd with SHIFT+arrows (up, down, left, right) or CTRL+SHIFT+arrows (left, right) and scroll the page with arrows. I want to do something nasty to the webdev each time I'm on the page which overrides those shortcuts. Especially when it's sth like redirect to other article on ARROW_RIGHT (sigh).

Fortunately I have "Disable JS" button right in the status bar...

TL;DR: do not mess with my keyboard or I will find you!
