I used to strive to keep my hands on the keyboard and only use the mouse when necessary, but this customized mouse kind of flipped that paradigm for me. Now anything I would have used a keyboard shortcut for in the past, I can do from the mouse. I incorporated several shortcuts that were new to me and several I was familiar with, but could never quite remember. Now I don’t need to remember the right combination of modifiers and letters or arrows on the keyboard; it’s all laid out on my mouse’s six keys in a way that is very logical (at least to me). I can quickly Shift-click; Control-click; Enter; Backspace; Delete; Escape; Tab; Refresh; Undo or Redo; cut, copy, & paste; switch apps, tabs, & virtual desks; control media; and so much more, without navigating the right-click menu, all from my mouse thanks to my custom firmware.
还有一个重要的指标——准确率。伯克利函数调用排行榜 (BFCL) 是评估函数调用能力的标准基准。 Gemma 3 1B 的得分约为 31%，Llama 3.2 1B 约为 26%，两者未经微调的性能都很弱。由于 Gemma 3n 是通用型程序，因此未对其进行测试。Hammer 2.1 0.5B 没有公开数据，但其 1.5B 版本开箱即用的得分约为 73%——尽管它在 int8 内存中占用约 1.5GB 的空间，是 FunctionGemma（288MB）的 5 倍。
