where in user guide to find directions for using option bar with various tools

[klj5]

I'd like to be able to read about how the option bar is used with whatever tool I might be using at the time. I suppose there's 2 ways of learning the option bar: trial and error, or reading instuctions. I prefer the latter, but as the option bar works differently with different tools, I don't know where to go to find specific instructions on using the options bar in conjunction with those various tools. Can anybody please point me to the instruction guide? Thanx.

Here is the user manual: https://helpx.adobe.com/photoshop/user-guide.html  and more specifically Adobe's help document on using the options bar can be found here: https://helpx.adobe.com/photoshop/using/using-tools.html

Use the options bar

The options bar appears below the menu bar at the top of the workspace. The options bar is context sensitive—it changes as you select different tools. Some settings in the options bar (such as painting modes and opacity) are common to several tools, and some are specific to one tool.

You can move the options bar in the workspace by using the gripper bar, and you can dock it at the top or bottom of the screen. Tool tips appear when you position the pointer over a tool. To show or hide the options bar, choose Window > Options.

To return tools to their default settings, right-click (Windows) or Control-click (Mac OS) the tool icon in the options bar, and then choose Reset Tool or Reset All Tools from the context menu.

For more information on setting options for a specific tool, search for the tool’s name in Photoshop Help.

Hi, in addition to the user guide, I also like to look on Julieanne Kost's blog: https://jkost.com/blog/2021/05/30-ways-to-customize-the-photoshop-interface.html

I know of no such documentation available from Adobe. 

But maybe I misunderstand what you are looking for.
