Macro to edit a cell in a column and go to the next cell below it.

Hi, i'm fairly new to excel and can't find a decent place to learn everything about macros so i'm just learning as per my needs.
Here i want to edit a cell in a column, and then go to the cell below it. I have created a button, so when i press that button, i want to edit a cell in the specific column and go to the cell below it, so that when i press the button the next time, the macro edits the next cell. Pls help asap.
Thanks.

What i want to do is, when i press the button, it should run a macro that should edit a cell. and when i press that button again, it should edit the cell below the previous cell.
Suppose, i press button, it enteres "Yes" in the first cell of a column, when i press the button for the 2nd time, it goes to the second cell and enters "Yes" in that cell as well.

Thank you so much, that worked

What should i do if i want to rotate the active cell in just a range of 100 cells of the column, and i dont want to have to click a cell and then click the button?

I have 2 columns, Date and Task, I want to press a button that would enter "Done" in a cell against a date. The next time i press the same button, it should enter "Done" in the cell below the previous one. My active cell could be anywhere in the sheet, but when i press that button, it should edit the next cell in that specific "Task" column.

PS. i dont know how to add a sample file.

Thank you so much, I dont understand how this macro is working though. Can you suggest anywhere online that i can learn about this?
