Source Id

Unique identifier of the source. Specific to dbopm.

Title

The title of the source.

Source Id

Clicking on a Source Id will open a "child" row for that source, showing additional information for that source.
The "child" row may also show a "More..." link, if more information is available. Click on the "More..." link to retrieve the extra information.
Clicking on the Source Id again will close the "child" row.

Pagination

Paging through the data is achieved by the First, Previous, Next, and Last buttons at the foot of the table,
or by entering a page number into the text input box labelled "Page".
The text input box labelled "Page" also accepts the left and right arrow keys to move between pages.

Row Selection

Rows of data may be selected and highlighted to assist in distinguishing items which may be of particular interest.
Clicking on a row will select and highlight that row.
When a row has been selected
- Shift + LeftClick will select a group of adjacent rows;
- Control + LeftClick will enable additional rows to be selected independently of each other.
Clicking on a selected row will deselect that row.

Searching (filtering)

Searching the database is accomplished via the individual column filters at the foot of the table.
The column filters are cumulative, so you can apply multiple individual column filters to combine search terms.
Note that the more complex the search, the longer it may take - although no search should take more than a few seconds.
All searches are case-insensitive.

Sorting (ordering)

Sorting is achieved by clicking on the column headings.
Sort sequences may be cumulative. That is, a simple one-column sort may be enhanced by Shift + LeftClick on one or more other column headings, thus adding secondary, tertiary etc. ordered columns.
The initial (default) sort sequence is alphabetic by Source title (ascending, i.e. A-Z).

Buttons

Source title lookup

This button provides a "lookup" facility, using an autocomplete and "Source title begins with..." search.

Searches are case-insensitive.

Restore

This button will restore the current data table to its original state, with all filters cancelled and the default sort sequence being reinstated.

Keyboard

Use of the apostrophe.: If you are unable to find an item which includes an apostrophe, you may be using an "apostrophe" character which dbopm doesn't recognise. Throughout dbopm, the "single quote" has been used to denote an apostrophe. On a standard English "QWERTY" keyboard, the single quote is on the same key as the "@" symbol. In technical terms, the character's decimal code is 39 (equivalent to hexadecimal 27 and octal 47).
