Multi-Edit (Edit Multiple Cells at Once)

When multiple cells are selected, typing affects all selected cells simultaneously with live preview and smart formula shifting.

How it works

1. Select multiple cells using Ctrl+Click or Shift+Click
2. Start typing — all selected cells show a preview of what they’ll receive
3. Press Enter to apply to all cells, or Escape to cancel

Formula Reference Shifting

When entering a formula with multi-selection, relative references automatically shift based on each cell’s position relative to the primary cell:

Example: Select D1, E2, F3 (Ctrl+Click), type =A1*2

While typing, you see:
  D1: =A1*2     (active edit cell)
  E2: =B2*2     (dimmed preview - shifted by +1 row, +1 col)
  F3: =C3*2     (dimmed preview - shifted by +2 rows, +2 cols)

Press Enter → all three formulas are applied with shifted references

Reference types

• Relative (A1): Shifts with each cell’s position
• Absolute ($A$1): Stays fixed in all cells
• Mixed ($A1 or A$1): Partially shifts

Fill Selection (Ctrl+Enter)

In navigation mode with multi-selection, press Ctrl+Enter to fill all selected cells with the primary cell’s content (with formula shifting).

Fill selection from primary cell	Ctrl+Enter
Cancel multi-edit	Escape
