For example, assume you are at the start of a new line. Pressing LEFT on the keypad does not move the cursor to the end of the previous line.
Similarly assume you are at the end of a line, pressing RIGHT on the keypad doesn't move the cursor to a new line.
How do I enable this behavior? Note this is the default behavior in Sublime Text 3.
Here LEFT and RIGHT are simply <- and ->, on the keyboard and not the numeric ones.

Let's say I want to place hyphen at the end of each line. I know I can do that by pressing Shift+Alt button in windows(to enable multiline cursors) and then jump to the end of line. (shown in the image below)
However, I want to place the cursor(and therefore hyphen) at the same position. In other words, I want hyphen to be below each another. Here is the pic of what I want -
Is there anyway to do this in vscode using multi-line shortcuts ?
Why do I want this ? To increase readability of my code.
Is there a way to make Emacs preserve my cursor's horizontal position, when going up and down between lines of varying widths in a file?
I'll explain what I mean by example. Say I have 3 lines of text:
1: ------a
2: --b
3: --c---d
Say the cursor is at the position marked above by a. If I move down a line, the cursor will be at b. If I move down again, it will be at c. But I actually want to end up at d.
Is there a way to make Emacs do that automatically, so that I can go from a to b to d just by pressing the down arrow twice? Emacs would have to remember my horizontal position from my most recent horizontal movement, and try to restore that horizontal position each time I move vertically.
Customize user option goal-column to nil.
(You can also use command set-goal-column anytime to set goal-column to the current column.)
In my current project I have a bunch of edit text boxes in my gui. When I/m in the first text blank and hit the tab key it skips to the third text box, when I hit tab again it goes to the second box. Every time I hit tab it jumps around in this weird order. I found out that the order is dependent on the order of the callback function for each text box. Without going in an copy pasting and changing around the code that gets generated by guide is there a better way to order my text boxes.
So for example when I'm in the box red x and hit tab it takes me to the box red z, than red y than green x then green z. I want to be able to click red x and then using just tab step through and fill out the other blocks. Is it at all possible to re-order?
GUIDE-generated GUI
When using GUIDE, you can simply use the "Tab Order Editor". Get to it using the following menu item:
For this simple GUI, with a single button and two text boxes, you would see the following dialog box:
Then set the tab order by moving UI objects up/down.
Programmatic GUI
To set the tab order programatically, you can use uistack to reorder the handles.
For example, to move a uicontrol "up" one in the order:
uistack(hui,'up',1)
To see the order of the handles to all controls in figure hf:
ch = get(hf,'Children')
I have an application that create lines on the cursor position. When I enter the datacursormode to create datatips, it create on the lines that follow the cursor position.
I was wondering how to remove them from being visible to the datacursormode, but don't making them invisible.
To solve it, make its handle HitTest off.
I.e, the line is created by a plot or line command, then add the following pair value at its end:
plot(…,'HitTest','off');
line(…,'HitTest','off');
This will make the line invisible for the datacursormode.
Hi I wrote a script with the "undotext" widget,
and I'm looking for a way to get the line index of the palce where the mouse cursor is standing.
and similarly when the user has select part of the line.
To get the current location of the mouse cursor in text coordinates (not just x,y) you need to do either this:
$txt->index("current");
or this (where $x and $y give the mouse cursor location relative to the text widget):
$txt->index("#$x,$y");
The first is definitely more convenient, but the second is needed if you're in the middle of a drag (the current mark isn't updated while any mouse button is down).
