The dash over the e, or accent aigu, (acute accent) emphasizes the final syllable in the word "resumé." In Microsoft Word 2013 and other word processing software, insert the acute accent from the menu or by using a keyboard shortcut.
Type "resum." Leave the cursor at the end of the word. Choose Insert from the menu bar.
Select Symbol from the Symbols group. In the pop-up window, choose é and then click Insert.
You may need to first click More Symbols for the pop-up window to appear after you select Symbols.
There are several choices for E. The acute accent leans right, not left.
When you click Symbols, recently used symbols appear. You can click any of the symbols in the box instead of opening More Symbols. After the first time you select the acute accent, it shows as recently used, and you can select it from the box.
The acute accent is inserted at the cursor.
Alternatively, use the keyboard shortcut to add the acute accent. Press Ctrl-' and then press E.
Other Word Processing Software
Open Office, Google Docs and LibreOffice provide a similar process for inserting the acute accent.
