Amazon’s Kindle relies on using the SYM button to input punctuation marks and special symbols. Unfortunately, this can make for slow typing when it comes to the usage of normal punctuation. By using these keyboard shortcuts, you can save a great deal of time when you need to use commas, apostrophes, colons, double quotes, and/or question marks.
Instead of using the SYM key, use the following keyboard shortcuts:
? (question mark): ALT+6
, (comma): ALT+7
: (colon): ALT+8
” (double quotes): ALT+9
‘ (apostrophe): ALT+0
