[Feature request] Option to move cursor in custom keys

[nimaaskarian]

it'd be really helpful if there was a way to set a move cursor string in a custom key definition.

For example, the key is defined as \leftrightarrow{%} and there is a property called set cursor, set to % which moves the cursor to % inside the brackets inside \leftrightarrow{<cursor is here>}.

abbr command of fish shell has some similar option (called --set-cursor). its good to take a look at. i'm not really good at android development, i'd make a PR otherwise.

There's already syntax to define a keystroke or gesture as a sequence of keys, including cursor movement keys. But it's not a real language with variables.

There's no way at present to make UK scan your input and make substitutions.

...including cursor movement keys.

i don't see the option anywhere.

and i'm not proposing scanning the input and making the subsitution, merely compile % inside \leftrightatrow{%} custom key to a cursor jump. so scan the custom key definition opposed to scanning the input.

Take a look at Possible-key-values.md for the new syntax and the valid keywords.

this is really interesting, thank you!

however i can't find a way to include \ in the string definitions. e.g. @/:'frac{}{} ',cursor_left,cursor_left works flawlessly, @/:'\frac{}{} ',cursor_left,cursor_left gets parsed as a string macro (idk what the term is here, but the whole macro definition is written when the key is hit)

i've tried the same thing with int:\int. the doc file you attached a link to says there's no need for escaping unless \ is being one of n or t (making it a newline or tab). i even tried escaping the \. it'd still write the whole macro definition.

It doesn't seem to work as I documented it. @Julow, what's the truth? How does one include \ in a key value?

Hi! Thanks for opening this issue and sorry for the slow reply. This should be fixed in #1126
Can you test the debug build at the bottom of this page ?

[nimaaskarian]

sorry for the late reply, i will test the debug build rn. thank's for the amazing keyboard, and for the response!

[nimaaskarian]

the debug build seems fine! i can use @/:'\\frac{}{} ', cursor_left,cursor_left macro to \frac{<cursor>}{}.

tho there is other problem, that each cursor_left call moves the cursor blocks to the left (which initially existed, but didn't seem like a big problem and i avoided it using an extra space at the end of the string macro).
