The Analysis Tools normally appear on the left of the main Vensim Window, although you can also configure them to appear along the top. When you click on an Analysis Tool, it will operate. This is the equivalent of turning a machine on after you have placed the material on or in the machine.
There are no keyboard equivalents for the analysis tools.
Some of the Analysis Tools can be locked so that they are automatically operated each time a new variable is selected into the Workbench. A locked tool will show as a depressed button. See the section "Locking Analysis Tools" below.
