Please be sure to have read the "readme.html" and/or the online docs coming with the plugin.
In order to activate the plugin, you need to enable Window / Customize Perspective / Other -> Quickmarks Both Styles.
Quickmarks are set using Ctrl+Shift+[0-9] (the keyboard shortcuts can be changed in Window / Preferences / Workbench / Keys -> Navigate.)
If a quickmark with the same number already exists, it is moved to the new location by default (unless there are duplicates already, then another duplicate is added by default). If the specific quickmark already exists in the current location, that quickmark is removed always.
You jump to a quickmark by pressing Alt+[0-9]. If the quickmark is not in the active file, the corresponding editor is activated (and the file is loaded if necessary).
In this order:
In some editors, you can't set marks at all, including by means of this plugin. This is particularly in the PDE-related editors (build.properties editor, plugin.xml editor etc). Other cases are editors opened via "Jump to Definition" (F3) and presenting you a class file, or files opened from the "Plug-ins" view. In the latter cases these editors also appear as read only. Although in all mentioned cases setting marks would be usefull too, Eclipse does not offer that functionality. So only an appropriate message is shown.
The versions 1.0.11 and 3.0.2 were implemented mainly by Georg Rehfeld. Thanks to Jesper for the initial version and all further support!
The plugin/package name has changed from 1.0.1 (formerly
dk.kampstruplinnet.quickmarks) to 1.0.10 (now
net.sourceforge.eclipsetools.quickmarks). So be
sure to remove
plugins when installing this variant to avoid conflicts (does
not apply to Eclipse 2.1, but only Eclipse 3.x).
