whitespace
The answer is
CTRL+R, CTRL+W : Toggle showing whitespace
or under the Edit Menu:
- Edit -> Advanced -> View White Space
[BTW, it also appears you are using Tabs. It's common practice to have the IDE turn Tabs into spaces (often 4), via Options.]
CTRL+SHIFT+* is the de-facto standard key combination for showing/hiding whitespace characters in all Microsoft products that support this feature.
P.S: * refers to 8- * key, not to numeric keypad * key.
If the Toggle Visual Space icon shall be added to a Visual Studio toolbar of your choice, because it shall be turned on and off via mouse click, then follow this instruction:
Customize the desired toolbar
Click on
Customize...Click on
Add Command...Go to
Editand choseToggle Visual Space
Click on
OK
Tested with Visual Studio 2019.
for VS code and later versions Ctrl + P to open and then writing Whitespace, you can select the View: Toggle Render Whitespace
In Visual Studio 2010 the key sequence CTRL+E, S will also toggle display of whitespace characters.
In Visual Studio 2015 From the top menu
Edit -> Advanced -> View White Space
or CTRL + E, S
