Reset workspace

Sometimes (especially after multiple DBeaver versions upgrade) the workspace can become messy. Some keyboard shortcuts may stop working, toolbar layouts may be broken, etc, etc. To reset all UI settings (this includes menus, shortcuts, view and toolbar layouts):

Shutdown DBeaver
Go to the default workspace folder .metadata\.plugins\org.eclipse.e4.workbench\
Windows: Win+R, enter %APPDATA%\DBeaverData\workspace6\.metadata\.plugins\org.eclipse.e4.workbench\
MacOS: open ~/Library/DBeaverData/workspace6/.metadata/.plugins/org.eclipse.e4.workbench/
Linux: cd $XDG_DATA_HOME/DBeaverData/workspace6/.metadata/.plugins/org.eclipse.e4.workbench/
Delete file workbench.xmi
Start DBeaver

If that does not help then you can try to remove the .metadata/.plugins/org.eclipse.core.resources folder.

If that does not help then remove the .metadata folder. It will erase all your UI settings (but all connections, settings and scripts will remain as is).

That is it.
