situation

If you are using an atom editor in Mac OS, you may need the Column Editing feature when editing a document.

For example,

good?!!
good?!!
good?!!

if there is such a document, the feature used when you want to change ? to ! at once is the Column Editing feature.

solution

Place the cursor in the first column of the position to edit, and press the ctrl + shift + down arrow key.
