[Chimera-users] Suggestion - autofilter history by typed substring?

[Oliver Clarke]

Hi Eric, I have been using the alterations you made to history navigation in Chimera and I like them a lot - they make it much easier to locate old commands.

I have one suggestion for a slight tweak… at the moment, scrolling up through the history (with Shift+Up) seems to update the string to filter on as I scroll. There is a (very) minor issue with this approach. It means the process is not reversible and the results depend on the contents and ordering of the history.

For example, lets say I’m looking for a command I typed a while back, i know it started with “bond” but can’t remember the exact name of the command. If I type “bond” and then hit Shift+Up, I will only find the first matching command - if I had both bondrepr and bondzone in my command history, for example, I will only see the first one. I think it would be more intuitive if history filtering paid attention to only the initially typed string, if that is possible - so if I type “bond”, I will scroll up through bondrepr, bond zone, bonddisplay etc, and will obtain the same results heading back “down” through the command history.

Cheers,
Oli.

This applies to both normal up/down and shifted up/down.  So, if you have several consecutive identical entries in your command history, this effectively treats them as one entry and therefore may reduce the need for a preference to not record consecutive identical entries in the command history…

If you use the shift key while navigating the command history (i.e. shift up/down arrow or control-N/P), then it will jump to the next history entry that matches the current command name.  Available in the next daily build.
