Presentation software allows me to show key sermon points to listeners.

An unexpected bonus of using presentation software has been a more disciplined editing of my sermon.

There are four types of files - word processing, presentation software, a spreadsheet program and software for producingforms.

Some web based slide shows are generated from presentation software and may be difficult to change (they are usually not supposed to).

It can usually be viewed through an appropriate editing program, such as word processing programs, database programs, or presentation software, depending on the file type.
