Is there a way to not select whitespace after a word when double-clicking?

Solution 1:

As far as I am aware, this is the default behaviour.

What I often do is to double-click the word and then hold shift and press the left arrow key (application allowing). I have found this to be the quickest method rather than attempting to precisely select the word under scrutiny with the mouse which is often a little tricky and fiddly.

Solution 2:

I double click on the word, but hold the second click and drag it slightly. For some reason selecting multiple whole words (double-click and drag) doesn't select the whitespace afterwards, so you can double-click and drag just the one word.
