What each tool in the left rail does, and the single-key shortcut to switch to it.

The tool rail

The left edge of the editor holds the tool rail. Exactly one tool is active at a time, and the active tool drives what clicking on the canvas means.

Tool	Key	What it does
Select	`V`	Pick pieces, drag selections, open the inspector. Drag in empty space pans the view. Default tool.
Place	`P`	Drop pieces from the catalogue dock. The ghost previews the next piece.
Flex Track	—	Place flex track. Coming soon — shown dimmed in the rail.
Measure	—	Click two points to read a distance. Coming soon.
Annotate	—	Drop text labels on the plan. Coming soon.

To delete track, select the pieces and press Delete (or Backspace) — there's no separate erase tool.

Flex Track, Measure and Annotate aren't built yet — they sit in the rail dimmed and labelled coming soon, and can't be selected until they ship. Their keys (F / M / A) are reserved for them, so pressing those does nothing for now. There's no Group tool — grouping is just multi-select (shift-click or a marquee) — and scenery is out of scope for the planner.

The top bar's cogwheel (next to the layout name) opens Layout settings — the board colour and snap step for the current layout.

What clicks mean in each tool

Select — left-click picks; shift-click adds or removes; drag in empty space pans; shift-drag draws a marquee. Press Delete to remove the selection.
Place — left-click drops the ghost; right-click (or Esc) cancels.

Middle-click drag and right-click drag always pan, regardless of the active tool. The mouse wheel always zooms.
