!! Workspace
Neither is it necessary to store all projects in the default workspace nor to have the project data there.

It is good to share different projects which have any relationships to each other in a single workspace. The workspace directory itself may hold only references to the projects.
To avoid the startup dialog where the user is asked for the workspace directory, one may also create a windows shortcut link into his or her project content directory. Specify the call to eclipse with an argument as follows:
 ....\eclipse.exe -data "here the path of the workspace for this project"
On the other hand: the startup dialog remembers which workspaces has been used until recent. The pop-down list allows quick workspace selection.

!! Keyboard shortcuts
For your own convenience, you may define own shortcuts, e.g. ctrl-ins and alt-bksp for clipboard insert resp. undo.
When you create a new workspace (automatically done for you when you point to a location where no workspace exists, these shortcuts are not automatically duplicated. To arrange this, use file->export on the original workspace and then file->import on the duplicate workspace in order to transfer the preferences, or only key shortcut preferences if desired.
