Summary  
This chapter demonstrates how to batch-assign a single value to multiple (even non-contiguous) data cells in one operation and how to implement input auto-completion based on existing entries.

General domain of usage  
Spreadsheet data entry and management

`Ctrl + Enter` (Win) or `control + return` (Mac) fills every selected cell with whatever you just typed — simultaneously.

#### The workflow:
Suppose you're adding a new **Status** column and every row in the current dataset should be marked `Confirmed`. Instead of typing it 50 times:
1. Select `G2:G51`;
2. Type `Confirmed`;
3. Press `Ctrl + Enter`/`control + return`.

All 50 cells fill instantly.
### Entering the Same Value in Non-Contiguous Cells
Sometimes the cells you need to fill aren't next to each other. `Ctrl + Enter` handles this elegantly:

1. Hold `Ctrl`/`Cmd` and click each cell you want to fill (or `Ctrl + Click`/`Cmd + Click` to select non-adjacent ranges);
2. Type the value;
3. Press `Ctrl + Enter`/`control + return`.

All selected cells — regardless of where they are on the sheet — receive the same value simultaneously.

### AutoComplete 
As you type in a column that already has data, Excel suggests completions based on existing values. This is AutoComplete — distinct from Autofill.


If column **B** already contains `Laptop`, `Mouse`, `Keyboard`, etc. and you start typing `La` in a new row, Excel immediately suggests `Laptop`. Press `Tab` to accept and move right — no need to finish typing the word.

Fill non-contiguous cells

1. Add a new column titled **Status** and fill it with `Confirmed` if you didn't complete it in the theory part.
2. Hold `Ctrl`/`Cmd` and click cells `K5`, `K15`, and `K35`.
3. Type `Pending` and press `Ctrl + Enter` / `control + return`.
4. Confirm only those three cells changed — the rest remain `Confirmed`.

You select K2:K51, type 'Confirmed', and press Enter. What happens?

As you type 'La' in a new row in the Product column, Excel suggests 'Laptop' via AutoComplete. You want to enter 'Label' instead. What should you do?
