Is it possible to change the default style and formatting for check box forms in Writer? I have to create templates for court forms, and I would prefer to have a check box than simply type X in a cell. The “3D” style looks out of place on court documents, so I would prefer to be able to set the default to flat. Ideally, I would like some sort of check box stamp which would permit me to simply add a check box where needed like a character. Is any of this possible?
Hi @farside268, Did @cloph’s answer work for you? If so, please consider marking it as ‘correct’. Thanks!
Unicode has corresponding characters - whether you can make use of them depends on what fonts you have installed.
There is U+25A1 WHITE SQUARE □ (and u+25a2 with rounded corners ▢ - U+2B1C WHITE LARGE SQUARE is rather new, so probably not included in your font 
), so probably a little too small for your usecase, and not meant for that anyway, more suited is: U+274F LOWER RIGHT DROP-SHADOWED WHITE SQUARE ❏ or U+2751 LOWER RIGHT SHADOWED WHITE SQUARE ❑ - and the favorite: U+2610 BALLOT BOX ☐
You can add autocorrect statement for those for example replace “[]” by the box character, and when you type <space>[]<space> it will replace it by the square character. Or an autoText, that you can then insert using bb<F3> for example (bb for “ballot box” - but you’re free to use whatever shortcut you like)
