1.1 What can you expect of button enhancers?

(Sometimes heavily) extending the number of applications you can start / tasks you can do with a hardware button by adding at least press-and-hold mode to the already-existing “short press” one. The vast majority of the enhancers add three additional states and there is one (HButton), which goes even further and lets for adding an unlimited number of different invocation capabilities to a button.

They, in general, contain widely asked-for goodies missing from the Windows Mobile operating system like a task manager (to quickly switch between running tasks), a task killer (to completely get rid of it to make sure it doesn’t take up any memory or other system resources), sometimes fancy, full-screen clocks (as opposed to the tiny one in the upper right corner) etc.

Note that you can freely download utilities like these. The most important repository of these free, but highly useful, single-purpose, small utilities is that of PHM PowerToys. The single-purposedness of these small applications also means these tools can be directly assigned to a hardware button (this is exactly what PHM Keys does). This also means that, if the particular button extender you select doesn’t have built-in for example Reset functionality (which can be very useful when assigned to a button, should you need to soft reset your device several times a day; a well-known situation for users of Resco Audio Recorder, which, in many cases, (at least on the Pocket PC platform) requires a reset after resuming the device and/or reinserting the sotrage card it should record to), you can always make use of Reset.exe of PHM PowerToys.

Incidentally, still speaking of the built-in Reset support of the reviewed button enhancers, none of them does prompt the user before resetting the device. Therefore, to avoid resetting resulting from an unwanted button press (you, for example, press it three times instead of twice and this triggers an unconditional soft reset), you may still want to prefer PHM’s version of Reset to the ones built into these button enhancers.

The case is pretty much different with the built-in task managers. In general, they’re better than that of PHM because you will have the time to select the task you’d like to switch to and, with the best task manager implementations, you can fine-tune its parameters.

Some (currently, two; one of these, buttonMax, still not being WM5+-compliant, doesn’t run on current Windows Mobile devices) of them let for defining application-specific shortcuts. These can be VERY important and useful. Just one example of this (which, also, explains where thee kinds of shortcuts can prove really useful):

Opera Mini (OM4 for short), with the latest, 4-series, has become a serious contender to all the other Web browsing solutions on out platform. Many even consider OM4 to be THE best Windows Mobile (WM for short) Web browser, particularly with a decent MIDlet manager (the environment to run MIDlets like OM4) like Esmertec’s Jbed.

OM4 (along with the still active 3-series) had, before the just-released beta 2, a very important problem: it doesn’t let for switching between full screen and non-full screen mode unless you have a built-in hardware dialpad or keyboard on your phone or, depending on the MIDlet manager you use (some, like Jblend, don’t support switching between the two screen modes using the on-screen keyboard; others like the, for running OM4, most recommended Jbed, can), can be bothered to bring up the on-screen keyboard to make the switch. If nothing works (you don’t have any kind of dialpad or keyboard and the on-screen keyboard isn’t supported by the particular MIDlet manager, you’ll need to find external ways of sending the “*” (or, in cases, the “**”) character(s) to OM4 to do the switching. It’s here that scripting solutions like MortScript come into picture: you just create a MortScript file containing a Sendkeys() function call, and just assign this script to one of your hardware buttons. After this, upon pressing the button, a *(*) will be inserted into the active program; if it’s OM4, then, it’ll force it to switch between the two screen modes. (Which, unfortunately, won’t work under the above-mentioned Jblend either, for reasons I’ll elaborate on in my forthcoming MIDlet Bible). Fortunately, with the latest beta, you can already get rid of the problem by going to Settings and make the changes yourself; but, again, this won’t help with the previous, 3.x-series still widely in use for the time being, that is, before the 4-series of Opera Mini leaves the beta status.

In addition to the full screen mode switching, OM4 has a lot of dialpad (numeric) key goodies like quick (page) up/down scrolling (as opposed to the default, line-by-line scrolling) when you use the 2/8 hardware buttons / keys. If you don’t have a handheld with these buttons / keys and you don’t want to open / slide out the keyboard (if it exists at all) to press 2 / 8 (the vast majority of Pocket PC’s, except for Asus’ phone models having a hardware dialpad, belong to this category), you’ll certainly welcome a solution that does the trick for you. That is, either an external program, tied to a hardware button, which you can invoke to send a 2 or 8 character to OM4, or a button handler, which itself can send your OM4 these shortcuts (for example, PQzII).

Yes, that’s at least two numeric key simulation functionality worth binding to a hardware key. And, if you would like to also bind the other, very useful numeric key-only shortcuts (see the complete list of them HERE, in the Opera Mini column) to hardware buttons, even more buttons would be needed.

If you bind these buttons to be active system-wise, then, you will quickly use up the really meager number of button configuration capabilities and you won’t really be able to make use of these configurations in any else program, where you won’t really need to enter, for example, 2 or 8 through a hardware button. This is (one example of) where application-specific button assignment can really pay off. You just use a button enhancer that is able to handle separate apps and only use button assignments with the defined one.

Note that, currently, not all applications can be treated this way. For example, as far as MIDlet managers are concerned (still sticking to the Opera Mini example), only those of Esmertes (Jeodek, Jbed) and TAO (Intent) will work. IBM’s J9 won’t work in app-specific mode (if at all: half of the devices I’ve tested it on keypress emulation wouldn’t work at all) and Aplix’s Jblend is the worst: it immediately pauses when you try to send something (for example, an emulated button press) to it. As VITO ButtonMapper, currently, doesn’t support sending out emulated keypresses (as has already been mentioned, it’s only PQzII that is capable of this feat), it must use an external tool (for example, MortScript) to generate keypresses, this means you in no way can send them to Jblend. Your only choice is PQzII, but the latter doesn’t allow for application-based, separate button assignment.

Another example of a program that cannot be used in separate, filtered mode is Opera Mobile 8.65, where using the numeric keys also greatly enhances the usability. This means you won’t

Many other WM programs, however, can be used in this “sandbox” model; therefore, VITO ButtonMapper still remains the number one button enhancer app to test when you want to have app-specific button assignments.

Please note that I’ll also elaborate on these issues in the “Hands-on experience: Passing keypresses to Opera Mini / Mobile” section. In there, you’ll get an even more thorough explanation of these questions and will also be presented some ready-made scripts.
