Why SpaceKey?

In daily typing, your hands frequently leave the letter area:

Arrow keys, Home/End, PageUp/PageDn — require reaching to the arrow key cluster
Symbols !@#$ — require stretching pinky for Shift + top number row
Shortcuts Ctrl+C/V/Z — require twisting pinky to hold Ctrl
Number input — require reaching to the number row or numpad

These may seem like small movements, but they add up to a lot of hand reaching and finger twisting over time.

SpaceKey's Solution

Your hands never leave the letter area while typing anything.

Hold Space with your thumb, and everything is right under your fingers:

Before (Traditional)	After (SpaceKey)
Reach to arrow keys for navigation	`Space + i/j/k/l`
`Shift + number row` for `!@#$`	`Space + s + g/o/n/d`
`Ctrl + C` to copy	`Space + m + c`
Reach to numpad for numbers	`Space + d + numpad layout`
`PageUp/PageDown` to scroll	`Space + f + i/k`

All operations happen within the letter area — no hand movement, no pinky strain.
