how to select all channels with shortchut?

[ART CORNER]

I want to use action. so, I want select all channels with the menu bar. so use in multiple files. I use the script for more than 100 files. all files have a different name in channels. i also attache sample of my channels.

Try this function:

selectAllChannels();

function selectAllChannels() {
    var totCha = activeDocument.channels.length;
    var actCha = new Array();
    for (var i = (totCha - 1); i >= 0; i--) {
        actCha.push(activeDocument.channels[i]);
    }
    activeDocument.activeChannels = actCha;
};

There may be a faster way with Action Manager code, however, I'm not the one to answer that!

P.S. Actions and scripts are different things. Once installed, the script can be recorded into an action. A custom keyboard shortcut can also be applied to the installed script.

Try this:

#target photoshop
try {
    if (activeDocument.mode == DocumentMode.MULTICHANNEL && activeDocument.channels.length == 3) {
        activeDocument.changeMode(ChangeMode.RGB);
    }
} catch (e) {}

really sorry,

but not working

[Stephen_A_Marsh]

Is the file in multichannel mode? Does the file have less or more than 3 channels?

The code previously posted checks for the file being in MC mode and only having 3 channels. You could try changing the check for 3 channels for greater than or equal to 3.

activeDocument.channels.length >= 3

Not working properly,

 result

i need like my video

can you make a script for it?

@ART CORNER – I was obviously assuming that you had 3 channels ready to convert directly into RGB, you never mentioned having 4 spot channels that you needed to convert into an approximate RGB visual equivalent.

Seems easy enough to record into an action or to script step by step via the ScriptingListener plugin as you already know what to do step by step...

#target photoshop
try {
    if (activeDocument.mode == DocumentMode.MULTICHANNEL && activeDocument.channels.length == 4) {
        activeDocument.channels.add();
        activeDocument.activeLayer.invert();
        moveChannel(1);
        activeDocument.changeMode(ChangeMode.GRAYSCALE);
        activeDocument.changeMode(ChangeMode.RGB);
        selectAllChannels();
        var idmergeSpotChannel = stringIDToTypeID("mergeSpotChannel");
        executeAction(idmergeSpotChannel, undefined, DialogModes.NO);
    }
} catch (e) {}

// Functions

function moveChannel(chaInd) {
    function s2t(s) {
        return app.stringIDToTypeID(s);
    }
    var descriptor = new ActionDescriptor();
    var reference = new ActionReference();
    var reference2 = new ActionReference();
    reference.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
    descriptor.putReference(s2t("null"), reference);
    reference2.putIndex(s2t("channel"), chaInd);
    descriptor.putReference(s2t("to"), reference2);
    executeAction(s2t("move"), descriptor, DialogModes.NO);
}

function selectAllChannels() {
    var totCha = activeDocument.channels.length;
    var actCha = [];
    for (var i = (totCha - 1); i >= 0; i--) {
        actCha.push(activeDocument.channels[i]);
    }
    activeDocument.activeChannels = actCha;
}
