Simple-Talk's free wallchart of the most important SSMS keyboard shortcuts aims to help find all those curiously forgettable key combinations within SQL Server Management Studio that unlock the hidden magic that is available for editing and executing queries.
The Keyboard shortcuts that are displayed in the wall-chart are based on what is on Books-on-line, but reordered and grouped in such a way as to make it easier to find what you're looking for. We've also taken out a lot of the keystrokes for navigating rapidly between various parts of SSMS that aren't related to the query windows, since this was intended more for the SQL developer. We added the SQL Prompt keys since SQL Prompt is so widely used.
The Wallchart is available from the speech-bubble at the head of the article as a PDF, but is also available as an HTML file, by clicking on the large thumbnail below. Of course, if you have eyes of cyborg-style pixel-density, you may get by just by reading the thumbnail below.
There was recently an amusing debate on ASK.SQLServerCentral.com as to which was the most important Keyboard shortcut. 'Save current window' one was voted highest. It is so much easier to do that than to use the GUI menus, so it is more likely to get done as a routine. However, you'll find many gems in this Wallchart.
