Keyboard shortcut to execute specific function from script

[Polycontrast]

I work with custom Photoshop scripts and keyboard shortcuts.

Is it possible to have a keyboard shortcut execute a specific function within a script?

and, another keyboard shortcut executes another function in the same script?

For example?

Citrus.jsx

• function pomelos(){}
• function lemons(){}
• function oranges(){}

Keyboard F1 executes the function Pomelos

Keyboard F2 executes the function Lemons

Keyboard F3 executes the function Oranges

[Kukurykus · Accepted solution]

Assiang F1 key to the script, basicly for pomelos function. When you want to trigger lemons then during refreshment change your finger from F1 key to F2. Similary if you want to initiate oranges, switch to F3.

refresh()

function pomelos() {alert(callee.name)}
function lemons() {alert(callee.name)}
function oranges() {alert(callee.name)}

({1: pomelos, 2: lemons, 3: oranges})[ScriptUI.environment.keyboardState.keyName[1]]()

[r-bin]

It seems to me that there should be an endless loop. Not?

Also swears at the line:

({1: pomelos, 2: lemons, 3: oranges})[ScriptUI.environment.keyboardState.keyName[1]]()

undefined is not an object

upd.

keyName == undefined

upd2.

It seems I misunderstood what the script does. Not a reliable method. And, if you remember, you can assign any number of hotkeys to the script, then everything is easier, but there can also be problems.

[Kukurykus]

Basicly save script to Presets / Scripts, relaunch Photoshop and assign F1 to appropriate item from File / Scripts. Then press F1 (for one second, that's the time of refresh()) so the script is going to call pomelos function. If you press F1 and then switch your finger to F2 or F3 for the time of lasting second it is going to call lemons or oranges.

I used it for some project and never had endless loop, and can't say why it could be unreliable if it always worked for me. To avoid one second of waiting after pressing the function key, you can combine it with BridgeTalk.

[r-bin]

Yes I understand. It is not comfortable. I can not. And it must be remembered that you need to keep the key (even F1) pressed for a while.

[Kukurykus]

Implementing BridgeTalk shortens time of awaiting for the result to milliseconds.

[r-bin]

Don't you consider the option with several hotkeys?

[Kukurykus]

Personally I used it fundamentally as F1 (for main part of script), also together with Shift, Alt or Ctrl for special options, or else combinations of them, when holding more keys beside F1.

[Polycontrast]

Thank you! I will investigate your suggestion and let you know how it goes.

[Polycontrast]

I use 5 separate script files that apply the same function to 5 separate Photoshop layers. 

Each script has its own keyboard combination key.

If the layer name is x then do function x.

I am trying to understand if it is possible to combine all 5 scripts into one main script and use separate keyboard shortcuts to execute a specific section of the main script. 

The Problem

Multiple script files

The solution 1

One script that responds to 5 separate  keyboard shortcuts

The solution 2

A loop that can detect the keyboard shortcut input and executes a function for the keyboard shortcut 

The benefit

One script file instead of 5 scripts

Have you considered this option?

Does it require building a UXP Photoshop panel?

And how would each button link to a specific function within the script?

Similar to assigning a unique ID to the button and the function to trigger the function?

By @Polycontrast

var f = null;
var d = new Window("dialog")

d.orientation = "row";

d.b1 = d.add("button", undefined, "Func1");
d.b2 = d.add("button", undefined, "Func2");
d.b3 = d.add("button", undefined, "Func3");
d.b4 = d.add("button", undefined, "Func4");
d.b5 = d.add("button", undefined, "Func5");

d.b1.onClick = function() { f = func1; d.close(); }
d.b2.onClick = function() { f = func2; d.close(); }
d.b3.onClick = function() { f = func3; d.close(); }
d.b4.onClick = function() { f = func4; d.close(); }
d.b5.onClick = function() { f = func5; d.close(); }

d.addEventListener("keydown", key_handle, false);   

d.b1.active = true; // otherwise a glitch 

d.show()

if (f) f();

function key_handle(e)
    {
    switch (e.keyName)
        {
        case "F1": d.b1.notify(); break;
        case "F2": d.b2.notify(); break;
        case "F3": d.b3.notify(); break;
        case "F4": d.b4.notify(); break;
        case "F5": d.b5.notify(); break;
        }
    }

function func1() { alert(1); }
function func2() { alert(2); }
function func3() { alert(3); }
function func4() { alert(4); }
function func5() { alert(5); }

He asked for shortcuts, not buttons 😉

[Polycontrast]

Thank you for the suggestion. The button panel would work best if the panel is a floating or dockable panel. I believe this can be done with a UXP panel.  Is possible to assign a keyboard shortcut to a UXPl panel button? 

This way the function can be triggered through the UI button or keyboard shortcut.

You know more than me. Why don't you try it yourself? What is "UXP panel"?

[Kukurykus]

UXP is something more experienced than that I think you didn't like, so CEP.

[Kukurykus]

You already explained in first post what you wish, and you got appropriate script. It does that you want, so what is problem? Did you even try it? That does exactly you are describing now.

[Polycontrast]

I have not to try yet, first, I must interpret it to figure out of to apply your suggestion.  It is not a simple process for me. Once I try it I can share my findings.

[Kukurykus]

Hmm, the script is finished, just replace content of functions for yours.

But before you replace anything inside, just run it to see how it works...

[Polycontrast]

I try the citrus.jsx script in Photoshop CC 2021 and get error 21 when I press the F1 key in a mac.

Then I get several erro 24 dialogs when I press F1 ket for one sec and then switch to F2 key.

What do these errors mean?

[Kukurykus]

Function keys don't work in Adobe applications | Mac OS

Insert into your script in the first line

alert (ScriptUI.environment.keyboardState.keyName)

[Polycontrast]

This is an interesting idea which I am not sure how it works.

The first F1 press produces the F1 alert followed by the Error 21 alert.

I was able to get the Lemons alert only once.

Why don't you like my script? The keys f1-f5 also work there.

You can also assign the same f1 key to the script call.

There is no need to do any special delays or tricks with your fingers.
