To accept all suggestions in Google Docs, click Tools > Review suggested edits, then click Accept all in the box at the top right. Click the Down arrow in that box first to preview the document with or without the changes. The Google Docs mobile app accepts suggestions one at a time only.
Google Docs has no page border setting, so you draw one. Click Insert > Drawing > New, draw a rectangle with a transparent fill, click Save and close, set the drawing to Behind text and stretch it to the page edges. For a simple frame, use a 1 x 1 table instead.
Google Docs can only copy comments when you copy the whole file: click File > Make a copy and tick Copy comments and suggestions. Copy-pasting text never brings its comments along. To copy comments into another or an existing Doc, use an add-on such as Merge Docs Pro with its Copy comments option.
To delete a page in Google Docs, click at the very start of the text after the blank page and press Backspace until the page disappears. If it won't go, turn on View > Show non-printing characters, then delete the page break or section break, or reduce the custom spacing that pushes text onto a new page.
To see resolved comments in Google Docs, click Show all comments at the top right, then click the All types filter and choose resolved comments. To restore one, click Re-open at the top right of the comment. Ctrl + Alt + Shift + A (Cmd + Option + Shift + A on Mac) opens the comment history.
To make subscript or superscript in Google Docs, select the text and click Format > Text > Subscript or Superscript. The shortcuts are Ctrl + , for subscript and Ctrl + . for superscript on Windows and ChromeOS, or Cmd + , and Cmd + . on Mac. Press the same shortcut again to turn it off.
