I created a form in backend like this:

I want to change save button text from 'Save' to 'Insert', here's my code:

Block\Adminhtml\Tools\Edit.php:

use Magento\Backend\Block\Widget\Form\Container;

        array $data = []
    ) {
        $this->coreRegistry = $registry;
        parent::__construct($context, $data);

    {
        $this->_objectId = 'tools_id';
        $this->_controller = 'adminhtml_tools';
        $this->_blockGroup = 'Lime_UploadFile';

        parent::_construct();

        $toolsId = $this->getToolsId();
        if (!$toolsId) {
            $this->buttonList->remove('delete');
        }
    }


    public function getHeaderText()
    {
        $toolsId = $this->getToolsId();
        if (!$toolsId) {
            return __('New File Item');
        } else {
            return __('Edit File Item');
        }
    }

    public function getToolsId()
    {
        if (!$this->toolsId) {
            $this->toolsId=$this->coreRegistry->registry('current_tools_id');
        }
        return $this->toolsId;
    }

}

Answer 1

You just need to add $this->buttonList->update() to update existing buttons of admin form in Edit.php

app/code/Vendor/Module/Block/Adminhtml/BlockClass/Edit.php

As per your code you can change save button label like this:

protected function _construct()
{
    $this->_objectId = 'tools_id';
    $this->_controller = 'adminhtml_tools';
    $this->_blockGroup = 'Lime_UploadFile';

    parent::_construct();

    $this->buttonList->update('save', 'label', __('Your Label Here'));

    $toolsId = $this->getToolsId();
    if (!$toolsId) {
        $this->buttonList->remove('delete');
    }
}

By this same way, you can change other buttons like save and continue, reset, back and other admin buttons

$this->buttonList->update('reset', 'label', __('Your Label Here')); //Change Reset Button Label
$this->buttonList->update('back', 'label', __('Your Label Here')); //Change Reset Button Label
$this->buttonList->update('saveandcontinue', 'label', __('Your Label Here')); //Change SaveAndContinue Button Label
$this->buttonList->update('delete', 'label', __('Your Label Here')); //Change Delete Button Label

Answer 2

This may help you. You can change your Edit.php file's _construct function as below.

protected function _construct()
{
    $this->_objectId = 'tools_id';
    $this->_controller = 'adminhtml_tools';
    $this->_blockGroup = 'Lime_UploadFile';

    parent::_construct();
    $this->buttonList->update('save', 'label', __('Insert'));
    $toolsId = $this->getToolsId();
    if (!$toolsId) {
        $this->buttonList->remove('delete');
    }
}
