This dialog allows you to edit the current month of the current time sheet. There are two views: "Chrono" (as shown) to modify the sheet, and "By projects" to sum up the time spent on the various projects.

To add a new row, check the place where to insert or append the row, and press "Insert". You can add more than one row by increasing the "Insert #" number. The new rows (like all other changes) must be saved (button "Save") to get permanent.

To delete rows, check the rows to delete, and press "Delete". (Checking the "append" places does not have any effect.)

To modify rows, just change the text in the input boxes. Input errors are detected immediately if Javascript is turned on, otherwise the next time you press a button.

To copy rows, check the rows to copy, and press "Copy". This writes the contents of the rows to the internal clipboard. Check the place where to insert the copy, and press "Paste". The clipboard keeps its contents when you change the sheet in the meantime. The clipboard does not remember where day breaks are, however.

To move rows, check the rows to move, and press "Cut". This moves the contents of the rows to the internal clipboard. Check the place where to finally put the rows, and press "Paste".

Your changes of the contents of the sheet are made permanent when you press the "Save" button. Until then, you can undo all changes by just leaving the sheet (e.g. by "Time Travel"). Just press "Discard" in the confirmation dialog.

If your web browser supports DOM level 2 very well, you can select a range of rows by clicking at the first row, and shift-clicking at the last row. This selects (or deselects) all rows between, too.
