I've been using SQL Server Management studio since long before it was called Management Studio, but I regularly stumble across some new feature or shortcut that I never knew existed.
Today I was querying several tables.
I then wanted to delete the contents of all of those tables. One trick I use is to hold down the ALT key to select a vertical column of text. I use this to highlight the "SELECT *" text on all of the lines at once.
I am then able to delete the selected text for all lines.
So that part I knew. But now I wanted to put the word DELETE at the beginning of each of the lines. Normally I would copy and paste it on every line. But this time, I just started to type the word DELETE.
As I typed, the characters appeared on all of the lines simultaneously! The thin gray line is the former selection area, and it essentially turns into a giant vertical cursor on all of the lines.
So I just typed the word DELETE once, and it appeared on all lines. Presto!
I just tested this technique in my UltraEdit text editor, and it worked there as well. It did not work in MS Word though.
