Two forms of the character for "inside"

When I first learned the character for inside, I was taught the form 裏, which I will refer to as the "tall" form. In Taiwan, I eventually discovered it had another form (from TV program subtitles, I think), 裡, which I will refer to as the "wide" form.

Someone taught me that the components of the wide form were equivalent to the components of the tall form. Starting with the tall form:

Take away from its middle the 里 (lǐ) component:

Join the two remaining components (the "lid" and the bottom part), and you get 衣 (yī), the character for clothing:

Thus, the first form has both 衣 and 里.

The wide form:

has, on the left, the radical for 衣 (the way it is written when it is the left component of a multi-component character), and on the right, 里. So the wide form also has both 衣 and 里.

My handwritten wide form tends to look less awkward than my tall form, and I've been using it almost exclusively for many years. That may make my usage a bit safer, because I know of one case where the wide form seems preferred over the tall from (or perhaps only the wide form is correct). The wide form can be used to mean the lining of clothing, and the inner lining would be 內裡 (nèilǐ), wherein 裡 isn't actually used to mean inside.

Recalcitrant iPod Home button and AssistiveTouch

The Home button on my 4th generation iPod Touch running iOS 5.1.1 has gotten inconsistently responsive over time. It no longer consistently registers a single press, or a double press, typically necessitating repeated presses beyond what the number which should be normal. At times I press it once, but that registers as a double press. completely failed. The degradation of response is no surprise to me. The device is a replacement remanufactured one, which I got from Apple at no charge near the end of the one year warranty period from my original 4th generation iPod Touch purchase. At that time, after confirming that it had not been immersed in water (there's an internal indicator for that), the Apple Store employees agreed that its Home button response had degraded badly enough to merit a hardware replacement. The replacement's Home button worked great for several months, but apparently the honeymoon (and, more significantly, the 90-day free replacement period) is over. (Interestingly, I don't remember noticing this problem with my 3rd generation iPod Touch, which I had also used under iOS 5.1.1.)

I stopped into an Apple Store and asked a floor employee (I didn't have a Genius Bar appointment) about possible remedies. The fellow I spoke with introduced me to iOS 5's AssistiveTouch, of which I was only dimly aware, if at all (It is documented in the iPod touch User Guide For iOS 5.0 Software, and probably elsewhere as well). It can be set in:
Settings > General > Accessibility > Physical & Motor > Assistive Touch
I also activated Triple-click Home > Toggle AssistiveTouch. (After the Home Button completely stopped working, I changed this to Triple click Home > Off since I needed the AssistiveTouch button all the time.)

AssistiveTouch wasn't intended as a fix for a recalcitrant Home button, but it works pretty well for that. When it's active, the AssistiveTouch button appears in one of 8 positions for the pre-5th generation iPod Touch: 4 along each of the left or right edges of the screen. The longer screen of the 5th generation iPod touch may add 2 more positions. Drag the AssistiveTouch button (even part of the distance) to change its position; it will jump to the new position.

It will likely be helpful to have a usual position for the AssistiveTouch button, so your finger automatically knows where to go. For portrait mode, which I use far more often than landscape mode, the 4 positions in the lower half of the screen are a poor choice, since they can interfere with keyboard input. When using the iPod with one hand, the 2nd position down on the left was a comfortable position for my left thumb. You might, as I did, rearrange apps and app groups on your various Home Screens to work better with the AssistiveTouch button's normal positioning. You can still open an app which is obscured by the AssistiveTouch button, but you will have to be more precise with your tap.

The concentric circles in the AssistiveTouch button are opaque white when it's first activated. After a short time, those circles and their square background become translucent, allowing easier identification of the area of the screen behind. The AssistiveTouch button is thus normally always present on the screen, either opaque or translucent -- you might want to turn it off before, e.g., watching a video. Screenshots are regrettably heavily obscured by AssistiveTouch, although some options supposedly exist for getting around that obscurement if you jailbreak your device.

Tap the AssistiveTouch button to bring up the options, one of which is a software version of the Home button. Tap that once or twice as desired, just like you would the hardware Home button. With AssistiveTouch I could make one additional tap (to bring up the options) and then do a single or double tap of its Home button, or I could make some unpredictable (because I never really know how any given tap will register) number of taps of the hardware Home button to do the same thing. I use the hardware and software Home buttons at different times, and am pretty happy doing so.

Depending on usage, I sometimes drag the AssistiveTouch button elsewhere (because I need access to the area of the screen where it had been sitting), but much of the time it's fine on top of the position of the app (or app group) sitting in the second row and first column of a Home Screen. When drafting this revision in Notespark, it was useful to move the AssistiveTouch button to the upper left corner, the lone position out of the 8 possible which would not interfere at all with my text editing.

The software Home button is additionally quieter than the hardware Home button. It's also more gentle/discreet to, from the AssistiveTouch options, tap Device > Shake, instead of physically shaking the device (e.g., to Undo Typing).
