Unselecting
Menu: Edit => Unselect objects …
Short key: Ctrl+U
To unselect a source from a previous selection, click on the corresponding source
while holding the Maj key.
To unselect all sources, i.e. empty the measures table, one has to click in the view
anywhere outside a source or use the menu “Edit => unselect all sources”.
Tip: In order to avoid loosing accidentally a selection, you can click the sources in the
table so that you can re-select them afterwards (see section below).
Counters
The number of selected sources (i.e. the one for which sources are displayed) divided by
the total number of sources is given with the counter on the bottom right of the Aladin
window.
Browse through the measures
Exploring measures and most noticeably viewing rapidly the associated sources is done
thanks to the selection of the specific line in the table of measures. The selected line
appears with a blue background “glued to the line”, even if the mouse is not over it.
Selecting a line of measure is done either manually or with the research expression.
Select a line of measure with the mouse
Selection with the mouse is done either in the measure panel with a simple mouse click
(outside a web link or a button), or by clicking on a selected source in the view (green
squares). It leads to a move of the Reticle (magenta cross) on the corresponding sources.
When the selection was done through the table with a double-click, the view is
automatically centred on the source (unless the view was locked - see 5.1.2).
Reminder: to redisplay the view globally, use Ctrl+ click in the zoom panel.
