Tool Modifier list (eg brush + alt-right click)

[RonInVan]

Is there a list of tool modifiers? For example, when using the brush tool, alt-right click changes the cursor to a preview of the brush size that you change by sliding left or right. A great feature! But I don't know where I learned about it.  It leaves me wondering what other tool modifiers are available.  There is a great list of keyboard shortcuts.  But I haven't found a list of tool modifiers.  That is,  a list of tools that shows what modifiers are available for each tool.

Closest thing I could find is this page: https://helpx.adobe.com/photoshop/using/default-keyboard-shortcuts.html

That has a lot more than just modifier key functions, but I guess you can sort of find all the ones you're talking about by searching that page for the following terms:

• "Alt-click"
• "Control-Click"
• "Shift-Click"
• "Alt-drag"
• "Control-Drag"
• "Shift-Drag"
