SikaiCase Custom Programmable Mechanical Mini Keyboard – 4 Keys

The SikaiCase 4-Key Wired Programmable Mini Keyboard gives frequently used shortcuts a compact, dedicated place on your desk. Choose a ready-to-use labeled version for Copy, Paste, Cut and Select All, or a blank-keycap version that you can configure for your own workflow.

Choose Your Style

The labeled version can also be reconfigured later if you prefer different functions.
