Have you considered using initialization cells? You could set the
property of all the cells before your working cells as initialization
cells by selecting them and using the menu command

Cell | Cell Properties | Initialization Cell

and unset the cells after your working cells by a similar procedure if
necessary. Then, each time you want to check things, you would just use
the menu command

Kernel | Evaluation | Evaluate Initialization
