Centering the Cursor

zz, zt, zb — move the viewport, not the cursor.

Keys: zz, zt, zb

zz centers the cursor's line on screen. zt scrolls so the cursor's line is at the top. zb scrolls so the cursor's line is at the bottom.

After a search jump or function navigation, the cursor often ends up at the top or bottom edge of the visible window — too little context. Three commands fix that without moving the cursor: zz, zt, zb.

Worked example — zz

Bring the current line to the center.

Step 1 · Cursor near the bottom of the visible viewport.
Cursor near the bottom of the visible viewport.
Step 2 · zz · zz — line moved to center, screen scrolled.
zz — line moved to center, screen scrolled.

zt puts the line at the top; zb at the bottom. The cursor doesn't move in the buffer — only the viewport.
