What punctuation "tricks" do you have in your literary arsenal and how do you use them?
Some are listed below. Keep in mind that by "tricks" I've taken it to mean "non-standard grammar" and so while I can write what I like (I have no teachers grading me), English teachers may take a dim view on their use.
Punctuation tricks? I'm going to answer this as an opinion piece and not as a strict grammatical exercise!
I like to use hyphens - probably too much (like I did just now). I find that it helps to set things off in a way that I just can't achieve with a period, a semicolon, or a parenthetical.
Periods can be fun to use when they show up where they are unexpected. It gives a stuttering, almost hammering effect to writing. One example that seems to show up in texting a lot is the use of "Oh. My. God." Compare that to "OMG" - which just flows off the tongue. The periods make the reader take notice of each and every beat in each word.
I like "asides" - places where someone who is saying one thing to someone can silently muse on the topic at hand. For instance, I could say: How did I find spirituality? Well... it kinda found me! (But how was it that it found me? And what was it that found me? And if I was found, was I lost in the first place???)
And that example brings up a couple more things - one being my love of "..." - it gives a pause, a quiet interlude of contemplation. It allows the reader to see that as a writer/narrator, there is a bit of contemplation occurring. See the above example to see the effect - that pause between "Well" and "it kinda found me".
Another thing I like to do is use multiple question and exclamation marks to highlight I've reached the end of a musing. Again, in that last example (which is now two tabs up), the last musing ends with three question marks - it's the last musing and, in a sense, if there were a punchline or summing up point, this highlights it.
Always keep in mind that what I've just listed doesn't always comply with standard grammatical rules - it's the occasional misuse of those rules that force a reader out of themselves for just a second, to take notice of a certain bit that as a writer I'm trying to highlight. But often (not always, but often) English teachers take a dim view to non-standard grammar!
