Guideline 5 in Guidelines for keyboard navigation in the sidebar [1] states: "Use Escape to go back one step in navigation, meaning from the content to the content panel title and then to the document." Current Escape key behavior from panel content moves focus to the panel title [2] but not from panel title to the document. Would also using Escape to move to the document from content panel tool box [...], deck title, deck title tool box [x], and tab bar be desirable? [1] https://design.blog.documentfoundation.org/2017/02/16/guidelines-for-keyboard-navigation-in-the-sidebar/ [2] There is an exception to this when the sidebar is floating and Escape key is pressed in Properties deck Style panel paragraph styles combobox and Character panel fontname and font size comboboxes. In these cases focus is moved to the document.
A patch to provide this behavior is here: https://gerrit.libreoffice.org/#/c/62808/
