The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

Business apps are keyboard centric, not mouse centric.
The browser is not made for this.
I tend to agree that database maintenance is keyboard centric as a generalization, while inquiry is mouse centric as a generalization.
Browsers not made for this? Well, I think that's where rich UI toolkits may come into play. They add both keyboard and mouse capabilities.
That's something that appealed to me when testing the Ext js grid component. It supported both keyboard and mouse options for record navigation and selection.
Arrow keys - select next / prior row
Home key - select first row
End key - select last row
Shift + arrow keys - select a range of rows, one at a time
Ctrl + shift + home - select a block of rows
Ctrl + shift + end - select a block of rows
Shift + click - select a block of rows
Ctrl + click - select multiple rows, not necessarily a block
Ctrl + a - select all rows
That said, I'm not completely sold on rich UI toolkits. Mostly because you may get saddled with features which use CPU and bandwidth unnecessarily.
Consequently, I've been working on something comparable to the Ext js grid, but scaled back, feature wise. I may be able to post an example later today.
