Move between neighboring Shapes without the mouse
Small Shapes are hard to hit precisely, and Shape List order may not match their layout on the Image. Reaching for the mouse between keyboard edits breaks the review rhythm.
In Labelme v7.6.0, press Ctrl+Arrow on Windows or Linux—or Command+Arrow on macOS—to select a visible neighboring Shape in that direction. The canvas and Shape List stay synchronized, so the next edit applies to the Shape you can see.
Navigate by position, not list order
Labelme compares the centers of the selected Shapes with visible candidates in the direction you pressed. It favors candidates aligned with that direction, so a same-row neighbor beats a closer diagonal one. If nothing lies that way, the selection stays where it is.
With no Shape selected, the first directional command starts at the visible Shape nearest the Image's top-left corner. Hidden Shapes are skipped.
The neighbor-selection implementation and directional checks cover all four directions, the synchronized Shape List, hidden Shapes, empty selection, and no-neighbor behavior. The four bindings are configurable under shortcuts; the keyboard shortcut guide explains the rest of the editing keys.
