1. Type a sentence/paragraph and hit return. 2. Type some spaces or tabs. 3. Place cursor at the end of spaces or tabs. 4. Ctrl+Shift+Left 5. If there is no period (punctuation) in the sentence of step 1 then the last word is included in the selection. If there is a period then that is selected. Expected behaviour: Only spaces or tabs at beginning of sentence/paragraph should be selected. Various other programmes behave in this manner. I don't know what should happen in the case of spaces or tabs in the middle of a sentence. Other programmes include the word prior to the spaces in the selection.
