Add select previous

[Ryan1729]

Given I have a word selected like so:

One word, two word, red word, blue word

I would like a keyboard shortcut that adds the immediately prior instance of that word to the selection, so the state after hitting that shortcut would be:

One word, two word, red word, blue word

This would be the opposite of the current find-and-replace:select-next feature.

Issue #324 seems to suggest that this feature was available at one point but since there is not a reference to it in the current menu or keymap cson files, it seems to have been removed at some point? Or was that referring to the distinct feature find-and-replace:find-previous that is currently bound by default to cmd-shift-g?

Using that feature in from my initial example state results in the following:

One word, two word, red word, blue word

which is not what I want.
