(Shift)+Shortcut+Left/Right skips one too many word boundaries.

[JordanMartinez]

Given the sentence below where "|" represents the caret:
I love cho|colate ice cream.

Pressing Shift+Shortcut+Left/Right will select the remaining word and either the leading or trailing word boundary (angle brackets used to show selection ""):

• Right once: I love cho<colate >ice cream. instead of I love cho<colate> ice cream.
• Right twice: I love cho<colate ice >cream.
• Left once: I love< cho>colate ice cream.
• Left twice: I< love cho>colate ice cream.

Similarly, pressing Shortcut+Left/Right:

• Right once is I love chocolate |ice cream. instead of "I love chocolate| ice cream.
• Right twice: I love chocolate ice |cream.
• Left once: I love| chocolate ice cream.
• Left twice: I| love chocolate ice cream.
