MacOS – Global convert to uppercase and lowercase in macOS

macosshortcuttext;

In Mail.app and Text.app there's Edit > Transformations:

Make Upper Case
Make Lower Case
Capitalize

…but I see no keyboard shortcut options in:
System Preferences > Keyboard > Shortcuts:: Services.

Is there a way to get this functionality available globally for all text entry? For example, web based forums like Stack Exchange.

Of note, the options are available in Safari.app's Edit > Transformations menu:

…but not in Chrome.app:

I could change my browser habits, but it would be nice to know if there is a way to add this functionality to all "Edit" menus.

You can do it in Safari, but Chrome ignores the standard Mac Toolbox, unfortunately.

System Prefs > Keyboard > Shortcuts > App Shortcuts

You can set key commands for All Applications, which will then work for all that have the requisite menu option.

This is my own setup, which shows keys already set for Capitalise & Lower Case
I use it a lot for such as Stack Exchange.

All you need to do is install KeyRemap4Macbook.

From the "implicit behavior" section:

Share state of modifier keys with all connected keyboards:

When you are using multiple keyboards, modifier keys are shared with all keyboards.

For example, pressing "shift key on keyboard1" and "space key on keyboard2" sends shift-space.

Yes, it works on other Macs too, not just MacBooks.

MacOS – Tool to transform text to all caps or lowercase

You can set this up as a right click service in automator as @Matthieu Riegler suggested.

Open up Automator.app and create a “Service” with this workflow.

enter image description here

Pay close attention to the checkbox up top, “Output replaces selected test”. After the workflow is in place and saved, navigate to “System Preferences-->Keyboard.” On the left hand side select “Services”. On the right hand side you will see the Service you created, in the example its saved as “UpperCase”. Then give it a shortcut by pressing “Add Shortcut” and give it what you would like. Tested in TestWrangler and TextEdit.

Script used in Automator:

on run {input, parameters}
set upperCaseString to ¬
    (do shell script ("echo " & input & " | tr a-z A-Z;"))
return upperCaseString
end run
