Keyboard Preferences

When pressing tab
People who are used to word processors might expect Tab to indent a row, while people who are used to spreadsheets might expect it to move to the next column. Use this preference to indicate which you prefer. Either way, Shift-Tab will reverse the direction, to outdent rows or move to the previous column. If you actually want to insert a tab character, press Control-Tab.
When pressing return
When pressing Return, you might want a new item or you might just want to move to the next line within the item you are currently editing. Whichever way you have it, you can press Option-Return to do the other instead.
When creating a new row, split current row at cursor
Suppose you have the text cursor in the middle of some row's text. If this checkbox is selected, then pressing Return to create a new row will move all of the text after the cursor into the new row. Otherwise the currently selected row will remain as it is and a new empty row will be created. Either way, you can do the reverse by pressing Control-Return.
New rows are created
Do you prefer structural consistency or visual consistency? Choose wisely!!
If Always at the same level is selected, a newly created row will appear at the same level as the selected row. This is more structurally consistent, but the new row might be created quite far away on the screen if the selected row has a lot of visible descendants.
If Indented if there are children is selected, a newly created row will appear at the same level as the selected row if the selected row has no children; otherwise it will be indented to the level of the row's children. This means new rows will always appear directly below the selected row on the screen, but may seem structurally inconsistent.
Apply named styles with
Named styles, listed in the styles palette, are automatically assigned keyboard commands. You can choose whether you'd like these commands to use the Function keys (F1 to F9), or Control and the number keys (1 to 0).
