How to paint cells

Building a range means marking which hands you play and what action you take with each one. You do this by “painting” cells on the grid.
1

Select an action color

In the action palette (right panel), click the action you want to paint with. For example, select “Raise” (green).
2

Click a cell

Click any cell in the grid to assign the active action to that hand. The cell fills with the action’s color.
3

Or drag to paint multiple cells

Click and drag across the grid to paint several cells at once. This is the fastest way to fill in a range.

​
Removing actions from cells

There are two ways to remove an action from a cell:

​
Use the eraser tool

  1. Click the eraser icon in the action palette.
  2. Click or drag across cells to clear them.

​
Click to toggle

If you click a cell that already has the active action, the action is removed from that cell.

​
Clear all cells

To reset the entire grid:
  1. Open the toolbar menu.
  2. Select Clear All.
  3. All cells are cleared. You can undo this with ⌘Z.

Painting tips

Build ranges top-down. Start with the strongest hands (top-left of the grid — premium pairs and suited broadways) and work outward. This mirrors how most ranges are structured.
  • Use drag for suited connectors — Drag diagonally along the suited portion of the grid to quickly paint suited connector runs (T9s, 98s, 87s, etc.)
  • Use drag for suited aces — Drag horizontally across the top row to paint suited ace combos
  • Check the combo count — Watch the combo summary below the grid to make sure your range size makes sense for the position

​
Auto-save

Every change you make to the grid saves automatically after a brief pause (500ms). You never need to click a save button. A small save indicator in the toolbar confirms when changes are saved. If you make a mistake, press ⌘Z to undo. RangeSharp supports up to 100 levels of undo, so you can safely experiment.
