The new PowerPoint Designer feature automatically generates design ideas on the new Design Ideas pane. By default, this pane appears on the right side of the slide and can be very useful for creative users:

When you create the process flow chart, process map, business flow diagram, or data flow diagrams and UML activity diagrams, you often need to add some text or labels to the connectors. Unlike many other free and commercial diagram drawing packages, Microsoft Office shapes provide extremely rich text formatting features.

If you create a diagram, graphic, or even flow chart with cyclic procedures, you can use predefined SmartArt graphics, but the Cycle diagrams set is very limited. Moreover, modification of SmartArt graphics is not easy, and sometimes you will spend a lot of time on even trivial changes. So, it is easier to create your own arrows in a circle diagram if you want to add a fresh look to your presentation.

Named ranges (also known as defined ranges) are a powerful feature in Excel that allows you to assign a symbolic name to a cell, range of cells, or formula. These defined names are a convenient replacement for the address of a cell, data range, or formula in other formulas, charts, diagrams, shapes, etc.

While working in Excel, you may need to find certain types of cells in your worksheets. For example, cells that contain comments, formulas, or only formulas with errors. See how to select all the embedded charts on the worksheet and how to select a large data range in one click in Excel.

Excel supports different formats for positive and negative numbers. You can combine text and formatted values to make the display more presentative. Another numeric format is a timestamp, and you can find a difference between two timestamps and display it in days, hours, and minutes. However, Excel does not handle well negative timestamp differences.

When you work with many graphical objects such as pictures, charts, text boxes, shapes, etc., it is sometimes challenging to select one of the objects - it can lay behind other objects, or it can be too small, etc.
Excel proposes an excellent feature named Selection pane to help navigate between different objects and groups.

All visual objects in the document, including images, charts, photographs, diagrams, and other informative non-textual (visual) content, require Alternative text (Alt text) descriptions. Adding alt text can help people understand the content of images, graphs, and other similar objects. Alt text is read aloud when a screen reader meets such a visual object.

It is now popular to create PowerPoint slides with diagrams or charts drawn using the chalk or marker effect. If you create slides with this effect, it will be great to create an agenda or other slides in the same style. For some PowerPoint slides, you can add a background image with a chalk or marker effect:
