Taking screenshots with Shutter in Ubuntu

Currently I'm taking a lot of screenshots and I was looking for a tool to speed up my workflow. After a little bit of testing I found that Shutter has all the features I need:

• You can capture a specific selection of the screen.
• You can configure a default selection of the screen.
• You can autosave screenshots in a specific directory.
• You can link Shutter to a keyboard shortcut.
