Vim Clutch

In an effort to shave off precious microseconds from the tedium of having to manually switch modes in his favorite multi-modal text editor, Aleksandr Levchuk fashioned a USB clutch pedal to do the job. Now, instead of typing an “i” to insert text or hitting “Esc” to edit it, Aleksandr need only tap or release the pedal to enter the corresponding mode. [via HN]
