I was recently converting a free ebook that was formatted as an HTML document to a DRM free .prc file for use on my Kindle. The text contained HTML numeric values to represent some of the text; for instance, the latin small letter a with acute (á) was represented by the HTML number á …these values did not convert well to the .prc format. I learned that the keyboard shortcut of Alt+0225 would result in the actual symbol of á.
The HTML number for these are &#nn; and can be converted using the keyboard shortcut of Alt+nn. For instance, if you encounter an HTML number « you can replace that with the actual symol of ½ using the keyboard shortcut Alt+171. If you want a smiley in an email that you’re writing to someone, Alt+1 … ☺
I was able to perform global replacements for all of the various &#nnn values in the soucre HTML document with Alt+nnn equivalents and then successfully converted the reformatted HTML to a nicely formatted .prc file.
I later ran across a list of 255 Alt+ keyboard shortcuts that Brown Thoughts posted that I suspect will come in handy so I decided to post them.
