How to insert alpha, beta, gamma, delta, and other Greek symbols in Word

To insert the alpha, beta, gamma and delta letters in a Word document, you have different ways:

   I.  Using the Symbol font:

This method is very useful when you need to insert symbols rarely and it works only for Latin or Greek letters.

Anytime, when you type the text in the Word document, you can switch to the Symbol font and use the corresponding Latin letters to enter Greek letters:

   1.   Click Ctrl+Shift+Q to switch your current font to the Symbol font.

   2.   Use symbols like normal font (e.g. in Symbol font keyboard button "a" equals Greek letter "α", keyboard button "b" equals Greece letter "β", ..., "l" -> "λ", ..., "w" -> "ω", etc.):

Note: This method works for inserting only one letter. Thus, if you want to insert several symbols, you need to repeat these steps for each insertion.

After entering one letter using the Symbol font, the next character is entered using the previous font.

If you click Ctrl+Shift+Q twice, Word does not switch to the previous font, and the Symbol font doesn't stop to work after the first entered symbol. Thus, you will need to change the current font and style later.

   II.  Using the Equation:

This way is perfect if you don't need to care about the format and compatibility with previous versions of Microsoft Office (a recommended approach for physical science and mathematics, which require a lot of math in the text with consistent fonts for all equations and symbols):

   1.   In the paragraph where you want to insert the symbol, click Alt+= to insert the equitation block:

   2.   In the equitation block without any additional efforts, you can enter any letter that you need just by typing \+Name of the letter:

Note: You can create a shorter name, see the point III.2.

   III.  Using auto-replace:

When you work with many documents and often need to paste one special symbol, you may not want to insert an equation each time. Microsoft Word offers a helpful feature named AutoCorrect. The AutoCorrect options in Microsoft Word propose two different ways to quickly add any special character, such as an alpha, beta, gamma and delta letter from the Greek alphabet, or even large pieces of text:

• Using the Math AutoCorrect options,
• Using the Replace text as you type function of the AutoCorrect options.

   III.1.  Using AutoCorrect for Math:

Using this method, you can benefit the Math AutoCorrect options without inserting an equation. To turn on or turn off the AutoCorrect of the Math symbols, do the following:

   1.   On the File tab, click Options:

   2.   In the Word Options dialog box, on the Proofing tab, click the AutoCorrect Options... button:

   3.   In the AutoCorrect dialog box, on the Math AutoCorrect tab, select the Use Math AutoCorrect rules outside of the math regions option:

After clicking OK, you can use any of the listed Names of symbols and Microsoft Word will replace them to the appropriate symbols:

Note: If you don't need the last replacement, click Ctrl+Z to cancel it.

   III.2.  Using Replace text:

Using this method, you can come up with some sequence to use for replacing it to the Latin or Greek letter. For example, to replace some Greek letter with not short names, it is possible to use:

To define the new, short names to some Greek letters, do the following:

   1.   Insert the symbol for which you want to define the short name, using the Symbol font and select it.

   2.   On the File tab, click Options.

   3.   In the Word Options dialog box, on the Proofing tab, click the AutoCorrect Options... button.

   4.   In the AutoCorrect dialog box, on the AutoCorrect tab:

• Ensure that the Replace text as you type option is selected,
• The selected symbol has been inserted in the With field. If you use the Formatted text, select this radio button:
  
• In the Replace field, type the sequence that should be replaced to the symbol,
• If such sequence doesn't used yet, click Add.

   IV.  Using a shortcut key:

Microsoft Word provides a way to define the shortcut key for the most often used functions. Thus, you can assign a shortcut for inserting the alpha, beta, gamma or delta letter:

   1.   On the Insert tab, in the Symbols group, click the Symbol button:

Note: If you use the character very often, you will find it in the Symbol dropdown list:

   2.   Click More Symbols....

   3.   On the Symbol dialog box:

• To insert the alpha, beta, gamma or delta from the current font (if exist), from the Subset dropdown list, select the Greek and Coptic:
  
• To insert the alpha, beta, gamma or delta from the Symbol font, from the Font dropdown list, choose the Symbol font:
  

   4.   Choose the symbol and click the Shortcut Key... button to open the Customize Keyboard dialog box:

   5.   In the Press new shortcut key field, type the key combination that you want to use for the symbol or character (e.g., for symbol δ used Alt+D) and click Assign.

Note: Be careful, you can reassign the assigned already shortcuts in Word. Be sure, that after Current assign to: there are no active Word functions. In any case, you can reassign any existing function in Word to a different key.
