vscode tab back code example
Example 1: how to left tab code in vscode
In Visual Studio and most other half decent IDEs you can simply do "SHIFT+TAB". It does the opposite of just TAB.
I would think and hope that the IDEs you mention support this as well.
Example 2: vs code open file shortcut
To open a file:
1. press ctrl + p
2. enter filename
3. To go to line append ":10"
4. To go to function append "@foo"
