Setting Proofing Language for Text in PowerPoint 2011 for Mac

English is spelled and pronounced differently in various parts of the world. For example, color is perfectly valid spelling in the US, but not so in the UK. And PowerPoint works different too depending upon which language settings have been specified. If your proofing language is set to English (UK), then the spell checker will suggest that the word color needs to be changed to colour. Also, if your text is marked as French, then both spellings of color/colour would be flagged as incorrect. Because then, you might be asked to change the spelling to couleur. Clearly, the fact that PowerPoint adds red squiggly underlines to properly spelled words can be a nuisance—but that's something you can rectify. In such situations, you first need to have proofing tools installed for all or any of the languages that you need to work within PowerPoint. Then, you need to follow these steps in powerpoint 2011 for Mac:

1. First select the text container you want to change the proofing language for, as shown in Figure 1.
2.

2. Now, select the Tools | Language menu option as shown in Figure 2.
3.

3. This brings up the Language dialog box that you see in Figure 3. Note that English (United States) is the default proofing language in this case, as indicated by its first position in the Mark selected text as list.

4. Scroll down the Mark selected text as list to select any other language. All installed languages are listed here as shown in Figure 4, below. Choose the language you want to use for your selected text container. In Figure 4 you can see that we selected French (France). Thereafter, click the OK button.

5. Repeat the process for any other text containers within your presentation.
6. Save your presentation.

If you want to set any language as the default proofing language, follow these steps:

1. First access the Language dialog box as explained in steps 1 and 2 in the preceding section.
2. Choose the language you want to use as the default proofing language.
3. Then, click the Default button (highlighted in red within Figure 4, above) within the Language dialog box. This will bring up a message window as shown in Figure 5. Click the Yes button in this window.
4.
