how do you change the color of the border of the selected cell navi thing..?

I’m using a spreadsheet with an all black background. I cannot see what cell is selected as the border of the selector thing is also black… is there any way to change the color? any thoughts?

From the menu, choose Format>Cells. In the Format cells dialog box, there in the “Outline” tab, you can make the settings for the border. In my example, I chose white.

The name field also shows you the cell in which the cursor is located.

With me Windows 10 Home; Version 1903; 64-Bit | LibreOffice, Version: (x64).

So, there is no way to change the cursor color?

Version - that dialog box on my screen does not show an “Outline” tab. Any other suggestions? Thanks…

Check “Borders” tab, from there you can add/change cells border and color.
