The following new features are now available in Google Docs:
Mobile editing: Log in to your Google Docs on a browser on a supported device, and select the document you want to edit. Then, when you’re viewing it, press the ‘Edit’ button to switch to the mobile editor. If you use an Android device with voice input, you can also use this to add text to your document.
Text replacements: We have added the ability to substitute text automatically and being able to manage the replacements.
LaTeX shortcuts in equations: LaTeX is a document markup language that’s often used by academics to quickly type out complex formulas. In Google Docs, when you’re inside an equation you can type ‘\sqrt’ followed by a space or a parenthesis to automatically convert the text into a square root sign √. Other examples of useful shortcuts are ‘\frac’ for a fraction and shorthands like ‘\epsilon’ for Greek symbols. Full list of equation shortcuts here.
Mobile editing: Over the next few days, we’re rolling this out to English-language users around the world on Android with Froyo (version 2.2) and on iOS devices (version 3.0+) including the iPad. We’ll be adding support for other languages soon.
Text replacements: You can right click on a misspelled word, go down to the ‘AutoCorrect’ option, and choose a way of automatically fixing this spelling mistake in the future.
