Align cells and wrap text

What it does

Select a cell or range and use the toolbar's alignment controls — a horizontal group (left / center / right), a vertical group (top / middle / bottom), and a wrap toggle — to place text inside each cell like Google Sheets. Horizontal alignment also has keyboard shortcuts: Ctrl+Shift+L (left), Ctrl+Shift+E (center), Ctrl+Shift+R (right).

Horizontal alignment defaults to the cell type — numbers, dates, and booleans hug the right, text hugs the left. Choosing an explicit alignment overrides that default (left-align a number and it moves left); re-choosing the alignment a cell already has clears it back to automatic. Vertical alignment defaults to bottom (Sheets' default) and is visible when the row is taller than one line.

Wrap breaks a value too wide for its column onto multiple lines at word boundaries (a word longer than the column breaks mid-word) and grows the row so every line is visible. With wrap off, long text is clipped at the cell edge and the row keeps its default height.

All three are presentation attributes, separate from the cell's value: aligning or wrapping =A1+B1 repositions the number without touching the formula. They are per-cell, survive value edits, and undo/redo like any other edit.

Verified behavior

Matches Google Sheets: In Google Sheets, horizontal alignment defaults to type-based (numbers/dates/booleans hug the right, text the left); an explicit Left/Center/Right (toolbar or Ctrl+Shift+L/E/R) overrides that default and re-selecting the current alignment clears it back to automatic. Vertical alignment (Top/Middle/Bottom, toolbar only) defaults to BOTTOM and is visible when a row is taller than one line. Text wrap breaks a value too wide for its column onto multiple lines at word boundaries (a word longer than the column breaks mid-word) and GROWS the row so every line is visible; with wrap off the text overflows/clips and the row stays default height. All three are per-cell presentation attributes: they survive value/formula edits, never change the computed value, and undo/redo like any edit. (Text rotation, also offered by Sheets, is a deferred follow-up — not built in this slice.)

Ctrl+Shift+E centers the selected cell

Given

• A1 = hello

When I click A1, then press Control+Shift+e

Then

• A1 is align=center

an explicit left-align overrides a number's automatic right-align

Given

• A1 = 42

When I click A1, then press Control+Shift+l

Then

• A1 shows 42
• A1 is align=left

alignment is presentation only — the value and formula are untouched

Given

• A1 = =2+3

When I click A1, then press Control+Shift+r

Then

• A1 shows 5
• A1 has formula =2+3
• A1 is align=right

alignment survives a value edit

Given

• A1 = x

When I click A1, then press Control+Shift+e, then type changed into A1

Then

• A1 shows changed
• A1 is align=center

alignment undoes and redoes with the command log

Given

• A1 = x

When I click A1, then press Control+Shift+r, then undo, then redo

Then

• A1 is align=right
