P: Ability to browse the presets and see its effects with the up and down keys

See this video for a demo of how hovering over a preset previews it in the navigator window: https://dl.dropboxusercontent.com/u/2...

You can easily prove this to yourself. Create a preset "Exposure" with just one setting, Exposure = +2. Create a second preset "Contrast" with just one setting, Contrast = +50. If you click Exposure and then Contrast, the photo will end up with Exposure = +2 and Contrast = +50, not with Exposure = 0 and Contrast = +50.

Many presets set some or all of the develop settings to their default values, so as you move from one to the next, you may not see the setting change (if it was originally set to the default value). You really can't tell which settings a preset will override without looking inside the preset's file to see which settings it contains (right-click it and do Show In Finder / Explorer, or use the Any Preset plugin).

Additionally, the current lightroom doesn't appear to have the hover feature you describe.

I'm not sure this is entirely accurate. I'm using some VSCO presets and this doesn't seem to be the case. Regardless if I start off with the original file or jump from a modification by a previous preset, the changes in the develop panel are the same. Can you share your specific experience? Thanks!

Would be absolutely FANTASTIC to be able to arrow through presets in lightroom and acr instead of having to use my mouse and click on every single one. Can't believe this hasn't been implemented yet. Would save me days...

Note that many people successively click on presets until they find one they like. This can have a nasty side effect, since LR doesn't automatically undo the previous preset before applying the current one. For example, if you click on a preset that sets exposure = +2, and then you click on another preset that doesn't change exposure, you'll be left with exposure = +2 (unless you hit undo after clicking on each preset).

This problem doesn't occur if you hover the mouse over the preset instead of clicking on it. But you only get to see the effect of the preset in the small navigator preview in the upper-left corner.

This functionality has been moved into the Any Preset plugin.

I agree. As a workaround, though, you could use the Any Source plugin to quickly search develop presets and to preview them using the up- and down-cursor keys.

Bummer. I know of one really expensive plugin that will do it (and not much else), but don't remember it's name atm. Maybe Adobe will support plugins responding to keystrokes in Lr SDK 5, then I'll whip you up something... ;-}.

the built in only allows for menu options. and I dont think that there are any ways in the menu to apply presets. It would be nice if when you are creating a new preset, there were a box that allowed you to assign a keystroke for it. say F2 would apply my custom BW preset and so on. keyboard tamer is also only for menu options.
