I've switched between different Excel keyboard shortcuts over the years, but one of them has been my mainstay since I was in college: Ctrl+1. This memorable keystroke is my backdoor for 80% of everyday and complex spreadsheet problems.
Ctrl+1 launches the Format Cells dialog box, the original main control panel that predates the modern Ribbon. Even today, it offers essential tools and controls that Ribbon does not. Once open, I quickly switch between tabs by pressing the first letter of the tab's name (eg A for alignment) and then use the Tab key to switch between the settings within.
When I first press Ctrl+1 on a new spreadsheet, the Number tab is the first thing I see, and for good reason. This is the default landing point because this is where most of the real Excel magic happens.
Features not available through the Ribbon allow me to program the appearance and behavior of my data.
Custom number formatting
The Excel ribbon icons only allow you to apply common formats, and creating complex conditional format rules is cumbersome. However, the Custom Ctrl+1 category allows me to quickly create display rules based on the strict syntax entered in the Type field, separated by a semicolon:
[Positive];[Negative];[Zero];[Text]
TO hide cell display While keeping the number active, I enter three semicolons (;;;) in the Type field. This makes the cell appear empty and the data remains untouched, which is useful for things like heat maps.
I also use the Custom option to apply simple color logic. For example, to instantly highlight negative values in red and positive values in green on the income statement, I would type:
[Green]$0.00;[Red]-$0.00;$0.00
Extended Date Formats
If the only options available on the Excel ribbon are Short Date and Long Date, Ctrl+1 allows me to define exactly how I want the dates to look. I often want to display the day and month, such as “Friday, December 12, 2025.” For this I use the following custom format:
ddd, mmm dd, yyyy
The key benefit is that Excel still recognizes this value as a valid date, meaning I can still refer to the cell in formulas.
Additional accounting options
Accounting categories and currencies provide much more precise control than tape:
- Symbols: I can choose from an extensive list of world currency symbols that are often missing from the ribbon.
- Decimals: I can permanently fix the number of decimal places for that particular format, ensuring consistency throughout my book.
- Loss values: In the Currency category, I can define how negative values will be displayed. This includes the ability to display them in red, which is important for audit-ready reporting.
Layout and cleanliness
When I open the Ctrl+1 dialog box, I press A to open the Alignment tab, F for the Font tab, and B for the Border tab to achieve a level of professional presentation that the Ribbon can't offer.
Center Selection (Merge and Center Killer)
I I almost never use Merge and Centeras it causes endless problems with sorting, filtering and pivot tables. Instead, in the Alignment tab, I select Center on Selection, which is accessed through the Horizontal drop-down menu.
This option aligns text in multiple selected cells without actually merging them, allowing me to perfectly center a row label or heading while maintaining structural integrity.
Accurate border control
Although the Excel ribbon gives me quick access to several standard border styles, the Border tab of the Ctrl+1 dialog box is the only place where I can define the style, color, and placement target all at once.
I can pinpoint the presentation:
- Style: Choose from a variety of lightweight weights (thin, thick, double, etc.).
- Color: Choose the exact line color that is critical for branding or differentiating sections.
- Targeting: I can apply unique styles and colors to the top, bottom, left, right, and inner borders in one action.
Pattern fills
The ribbon fill color is great for solid colors, but for professional datasets that need subtle background textures, I use a pattern fill.
From the Fill tab I can access:
- Pattern Style: Apply fine dots, shading or stripe patterns.
- Pattern Color: Control the color of the pattern itself, regardless of the background color.
Always choose a light pattern color so as not to obscure the text and numbers in the selected cells.
This adds a level of visual segmentation not possible in the Home tab.
Security: locked and hidden properties.
The Security tab in the Ctrl+1 dialog box is one of Excel's most powerful but underutilized features. I use it to protect my IP and ensure data integrity.
After pressing Ctrl+1 and then P I see two checkboxes:
- Blocked: Cells are locked by default. This means that if I protect the worksheet, these cells cannot be edited. I use this option to lock formula cells, leaving only the data entry cells open for input.
- Hidden: This is the key to protecting my work. If I check this box and then protect the worksheet, the formula inside the cell will be hidden from the formula bar. The user can see the result, but cannot see or copy the calculations I used.
These checkboxes only set potential for protection. The actual execution only happens when I click “Protect sheet» on the Review tab of the ribbon and confirm your security settings.
Ctrl+1 shortcut goes beyond cells – I can use it to format charts and shapes through the contextual formatting bar.
Formatting charts
By selecting the entire chart or an element within it and pressing Ctrl+1, you have instant access to advanced controls. For example, I can quickly set minimum and maximum axis values, adjust the distance between data points, or adjust trend lines.
Formatting shapes, images, and text fields
For non-data elements, Ctrl+1 is a shortcut for visual polishing. It offers quicker access to advanced options than the ribbon, allowing me to fine-tune the look without having to guess where a tool is hidden.
For example, I can quickly apply precise transparency percentages to fills, control shadows and 3D rotation, or lock the aspect ratio.
Why I love Ctrl+1
Ctrl+1 simplifies my Excel workflow, effectively handling most of my everyday and complex formatting tasks.
Here's why it's the cornerstone of my daily work:
- Universal control: Ctrl+1 works with cells, charts, and shapes, offering a single, consistent entry point for formatting any selected object.
- Exclusive features: This is the only way to enable important features such as custom number formatting and hiding formulas.
- General store: It combines the vast majority of formatting options into one keyboard-controlled dialog box.
- Workflow efficiency: It's more memorable than the right-click menu: when I press Ctrl+1, the last tab I used opens. speed up repetitive tasks.
“What about the other 20%?” I heard you ask. This is reserved for functions with special dialog boxes and managers, such as Data verification, That PivotTable Fields paneland more advanced tools such as Request power. Mastering the Ctrl+1 keyboard shortcut eliminates unnecessary mouse clicks, allowing me to focus the remaining 20% on high-level management and data analysis.
