You like to save time, right? And you care about puppies, true?
In design (or any business), time is money. Anything that can save a few seconds and eliminate tedium is a good thing. Shortcut key combinations do both.
Of course, designers typically fall into one of three camps when it comes to using shortcut key combinations. The first group use them religiously. The second prefer the mouse. The third would use shortcut combinations... if only they could remember them. If you fall into that third category, here's a list of text-formatting shortcut key combinations built into Adobe Illustrator:
Increase type size incrementally
Decrease type size incrementally
Increase leading incrementally
Decrease leading incrementally
Increase baseline shift incrementally
Decrease baseline shift incrementally
Increase kerning/tracking incrementally
Decrease kerning/tracking incrementally
Restore kerning to Metrics and tracking to 0
Toggle automatic hyphenation
Justify paragraph (except last line)
Justify paragraph (including last line)
So what does any of this have to do with puppies? Nothing really. We were just curious.
