Connect the start/stop recording to the capslock (numlock or scroll lock).
This will permit capture without having to point the mouse on a screen, and in fact doesn't require to view the screen at all. A finger can be kept on the button to start/stop at will. The LED on keyboard provides the visual indication.
This will help where the configuration is that the computer running saleae is on a KVM switch and the target system is part of a different computer. Then, by simply adding a direct keyboard to the saleae computer, it's ok to loose sight of or take your eyes off the saleae software.
If someone wanted, they could take this to the next level and wire a foot switch to a keyboard and have both hands free.
Otherwise, thank you for a very useful tool!
