MenuKey Hook

[Xeda112358]

After playing with an idea from shmibs over on Omnimaga, I created this little beast. It allows you to select menu items/options from menus you are not currently viewing. Or let me put it this way: Say you want to access the string menu a lot, but you don't want to constantly go to the menu. Wouldn't it be great if you could press a key combo and the string you want is suddenly right there? Well here you go :D

Anyways, to use:
-Send it to your calc
-Run it
-Any keyhooks will be replaced by this and the first part of RAM at appBackUpScreen will be used

Now got o a menu of your liking (like the string menu, for example), and press [ON]+[Vars]. That menu will now be your quick menu.
Anywhere in the OS, like the program editor, Y= editor, homescreen, or whatever, if you want a menu item from that menu, press ON+[number]. For example, to get Str7, press [ON]+[7]. Here is an example:

As you can see, you can set a number of menus to work with this. The only menus that will not work are menus with user defined vars. For example, the program list or app list.

Problems:
-After viewing the app list or program list, the hook temporarily stops working. To fix this, just view another menu

Is it possible to permanently patch the OS? It would be awesome if this feautre was allrady in OS even after a crash.

Actually, there are ways to patch the OS, but I am not sure how difficult this would be. Patching the OS is still a bit beyond me, though. If you've ever heard of zStart (a very powerful app) it does crazy things with the OS so that it still remains active after crashes (it also allows you to have awesome grayscale startup screens, font changing, automatic mode settings after crashes, and a bazillion other features).

Hey! I'm a newbie at asm but I'm pretty good at TI Basic. I wrote a math assistant program and then converted it to a app via the basicbuilder application for windows. Long story short, I have a app.

I would like to run the app when a key sequence is pressed, similar to MirageOS and its [ON]+[APPS] hook.

HOW THE HECK DO I DO THIS! I've been looking around all over the internet for hooks and how to use them and such... I have a small understanding of them but whenever I get sample code for a hook, it never works. I don't know enough about asm to debug the program, so I look for a new example. (I have a compiler and all that [I made a "Hello World!" program so I know it works]) Could you perhaps modify a keyhook program so that [ON]+[PROGRAM] starts an app? Idk if its useful but I'm using a 84+SE and my app name is AAAMathy.

If anything, point me in the right direction so I can make this keyhook. THANKS!

The only way i can think of is to create your own interrupt table with ISR and set the calculator to interrupt mode 2. Of course its asm. I could help you with that, but i will wait till Thunderbolt returns, because she will knows at least 10 alternative and better ways to do that. My solution has a downside- if you somehow reset your ram, the program that does that will be gone. But i dont think its a problem since if you do that your program will dissappear as well

okay cool! Also, I was wondering can the calc run "background" programs? Like a screen saver? That has a 1 minute countdown timer that resets with every key stroke? Then it would run a program to bounce a ball around or something then turn off the calc? Just a simpleish idea.

Sorry, I was gone for a bit... I emailed the creator of BB, but I have yet to get a response. The easiest way to activate an APP is to use a keyhook, but I will need to know how it is exactly that BB runs its assembly programs (and what RAM areas it might use) :/

As for running "background programs," you will have to use interrupts, but those get disabled at certain menus and must be rather quick. A ball bouncing around the screen should work, but it could really slow stuff down.

I thought once about screen savers. I think you dont have to make the actual screen saver within an interrupt, but just start a program with it. So for example after the counter gets to bla bla it backups what the screen saver will destory(like variables and stuff), then copies the running program ( if there is any) alsewhere, and starts the SS.
