! There are also many useful keyboard and mouse shortcuts. You can browse through your spreadsheet with the mouse or the cursor keys, including the <keycap>Tab</keycap> and <keycap>Backtab</keycap> keys which traverse to the next and previous table cell, respectively. <keycap>F3</keycap> edits a cell, <keycap>Esc</keycap> aborts the edit (reverting the cell to its previous value), and <keycap>F2</keycap> or <keycap>Return</keycap> stores the edited value (and does any necessary computations). You can force reevaluation of a cell by pressing <keycap>F2</keycap> while the cell is
! selected, and a double click opens a cell for editing. You can also just start typing when a cell is selected, to overwrite its current value. All editing is done in place, right there in the cell; there is no separate line edit control as in other spreadsheets. Cell indices and formulas are shown in the status line when you click on them.

! Rectangular ranges of spreadsheet cells can be selected by sweeping the mouse over them as usual. You can also click a row or column header to select the entire row or column. Such ranges can be deleted, cut, copied and pasted as usual. Using cut/copy and paste you can also transfer ranges between different instances of QCalc. Moreover, QCalc performs automatic adjustment of relative column and row indices in formulas. Thus, if you copy a cell containing the formula "<literal>= foo A1</literal>" to a position at an offset of, say, 2 rows and 3 columns from the original position, it will become "<literal>= foo D3</literal>". As usual, you can use the $ symbol to indicate absolute row or column indices (or both) which will not be adjusted.

! Rectangular ranges of spreadsheet cells can be selected by sweeping the mouse over them as usual, or by using the cursor keys while holding down the <keycap>Shift</keycap> key. You can also click a row or column header to select the entire row or column. NOTE: Selecting ranges of cells with the mouse or the keyboard can be hard to do if the cells contain editable GUI elements like comboboxes and spinboxes (see <xref linkend="basicguiops"/>). As a remedy, if you are not currently editing a cell, the <keycap>Esc</keycap> key allows you to switch the table from the default mode of operation to a special "read-only" mode. This mode is indicated by a tiny lock symbol in the status line. While the table is in read-only mode, editing operations on ranges of cells still work normally, but GUI elements are not activated when selected any more. This makes it much easier to browse the table and make selections with the mouse or the cursor keys. To leave read-only mode, either just press <keycap>Esc</keycap> again, or double-click on a cell or press <keycap>F3</keycap> to open a cell for editing.

! QCalc has an unlimited undo/redo facility, so if you mess up your spreadsheet you can always go back and forth in time as needed. These operations also adjust the table size as needed. They may also shrink the table if there is unused extra space; this also happens when you load a spreadsheet from a file. However, as already mentioned, QCalc always keeps the spreadsheet at a minimum table size of 128x26.
