Fiddler offers numerous ways to tag Web Sessions so you can easily identify them later. For instance, you can use the Comment button on the toolbar (or hit the M key) after selecting items in Web Sessions list to add notes about the traffic:
However, often you may find that you simply want to quickly mark some Sessions for later evaluation. To do so, you can use the context menu’s Mark submenu to choose a color:
The text of the selected entries will be bolded and colored as selected.
You may also press the CTRL+1 through CTRL+6 key-combinations to quickly mark the selected items.
Both comments and markings are stored in SAZ Capture files, which means they are great for bringing attention to specific Sessions when sharing a capture with others.
New to Fiddler 126.96.36.199 is the ability to quickly select all of the Sessions marked with a given color. Simply use the ALT+1 to ALT+6 combos to quickly select each group of color-marked Sessions.
I hope you find this new capability useful!
