I sent out a link to this on Twitter today and it was retweeted numerous times. Based on the Twitter response I thought it might be worth sharing on here too. Make Use Of has published a list of 14 Software Cheat Sheets and Posters. Covered in the list are Microsoft Office 2007, Firefox and Google Chrome use tips, Linux guides, Photoshop tips, and Twitter use tips.

Applications for Education
These cheat sheets and posters can be downloaded as PDFs and printed for use at home or at school. The posters could be very useful if they were displayed in your computer lab or in your classroom near your computer stations.
